Vulkan: SPIR-V Gen: Fix lvalues passed to in/inout parameters
In GLSL, these values are semantically copied when passed to a function
as an in or inout parameter. For example in:
bool f(inout vec4 a, inout vec4 b)
{
a = vec4(0);
return all(equal(a, b));
}
var = vec4(1);
bool result = f(var, var);
result is expected to be false. In SPIR-V, every parameter is
semantically passed by "reference".
glslang conservatively uses temporaries to pass to functions. An
optimization in ANGLE didn't create temporaries for unindexed lvalues,
which did not take into account the above fact. This optimization is
limited to out parameters now.

Vulkan: SPIR-V Gen: Support loops
Loops are similar to if-else in that they generate a number of blocks
where the first block specifies divergence (OpLoopMerge) and the merge
block. Differently from if-else, there is a block where the condition
is evaluated and a block which `continue;` leads to (this last block is
the only one allowed to back-jump to the beginning of the loop).

Vulkan: Generate SPIR-V directly from the translator; Part 1
This is the first change in a series to generate SPIR-V directly from
the translator's AST, instead of the generating text GLSL and feeding it
to glslang.
This change implements the majority of the work needed to map AST types
to SPIR-V types, and declare types and interface variables in SPIR-V.
Additionally, it lays the infrastructure to conditionally enabling this
path in end2end tests.
No tests are currently enabled as the change doesn't actually generate
code for function bodies yet.

Vulkan: Call glslang at compile time
With this change, the ANGLE translator immediately compiles the
generated GLSL into SPIR-V with glslang and discards the source. This
is in preparation for generating SPIR-V directly, by making the frontend
and backend already able to digest it.
This change also allows the expensive glslang calls to be parallelized,
improving the following perf test by about 20%:
LinkProgramBenchmark.Run/vulkan_compile_and_link_multi_thread
Previously, the test was run as such in the Vulkan backend:
Main Thread 1 Thread 2
Compile1 --->
Compile2 --------------------->
Translator Translator
<---

Link

With this change, it is run as such:

glslang_wrapper_utils no longer interacts with glslang! A rename will

Vulkan: Redo RewriteStructSamplers
This transformation is split into two. The first transformation solely
takes out the samplers out of structs, and potentially generates array
of array of samplers. A second transformation is added that takes any
array of array of opaque uniforms and flattens it.
A follow up change will simplify RewriteAtomicCounters which also
handles array of arrays (which is no longer possible), and removes
dependency on shaderStorageBufferArrayDynamicIndexing.

Vulkan: Initial emulated prerotation support
This is currently only supported for end2end tests (those which use
ANGLETestBase, excluding those that use WithNoFixture) and Vulkan. Use
WithEmulatedPreoration(*_VULKAN(), degree) where degree is either 90,
180 or 270.
With emulated prerotation, the window dimensions are physically swapped
if 90 and 270 degrees, while the width and height is still reported as
requested by the test. In the Vulkan backend, the width and height are
swapped after getting queried from the surface, and prerotation is
assumed.

Disable shader's pre-rotation code on Metal & non-Android.
Pre-rotation code were added to transform gl_Position, gl_FragCoords,
gl_PointCoords, dFdX, dFdY in shader. However, it is only useful for
android's surface pre-rotation and completely un-needed in Metal
back-end.
This CL disables these pre-rotation code if the platform is not
android.

Reland "Vulkan:Include precision qualifier in GLSL"
Currently still ignoring precision qualifiers for Vulkan shaders by
default, but have added feature "enablePrecisionQualifiers" that can be
enabled in order to include precision qualifiers.
With this initial implementation, it's possible to get precision
qualifier mis-matches in the generated GLSL 4.50. According to the
spec this is allowed. From GLSLangSpec 4.50 section 4.7 "Precision and
Precision Qualifiers":
For the purposes of determining if an output from one shader stage
matches an input of the next stage, the precision qualifier need not
match.
However, when converted to SPIR-V and run through the shader validation
any mismatches will cause shader validation errors. Initially just
ignoring those errors with this commit.

Vulkan: No line raster emulation code if extension
A flag is added to the translator to disable generation of Bresenham
line raster emulation code when the Bresenham line raster Vulkan
extension is present. This is primarily for the sake of conversion of
line raster emulation condition to specialization constant:
- Avoid dead SPIR-V code in every shader
- Avoid ANGLEUniforms being active in every shader stage even if it's
not used anywhere but in line raster emulation.
- Optimize SPIR-V transformations by both having fewer instructions to
iterate through, and to avoid generating line raster patches.
- Reduce the severity of anglebug.com/4251 where the location assignment
of ANGLEPosition can incorrectly overlap a varying array or struct, by
making only platforms without Bresenham extension afflicted by the
bug.

Vulkan: Improve cubemap emulation seam handling
Changes seamful cubemap emulation to always compute the derivative,
emulating the bias parameter by scaling the provided derivatives.
This results in more accurate mipmap levels for seams within primitives.
There are some artifacts as a result of how derivatives are calculated,
but this matches the native driver.

Vulkan: support dynamic indices in array of arrays
Expands existing struct-sampler rewrite to flatten arrays of arrays.
This allows us to support dynamically-uniform array indexing, which is
core in ES 3.2.
Samplers inside (possibly nested) structs are broken apart as before,
and then if the type resulting from merging the array sizes of the field
and its containing structs is an array of array, the array is flattened.
Also adds an offset parameter to functions taking in arrays to account
for this translation.
As a result of outer array sizes leaking into function signatures,
functions taking arrays of different sizes are duplicated according to
how the function is invoked.

Vulkan: Emulate subgroup ops in seamful cubemap emulation
Where subgroup ops are not available, they are emulated as such:
Code with subgroup ops:
float lH = subgroupQuadSwapHorizontal(layer);
float lV = subgroupQuadSwapVertical(layer);
float lD = subgroupQuadSwapDiagonal(layer);
bool isHelperH = subgroupQuadSwapHorizontal(gl_HelperInvocation);
bool isHelperV = subgroupQuadSwapVertical(gl_HelperInvocation);
if (gl_HelperInvocation)
{
layer = !isHelperH ? lH : !isHelperV ? lV : lD;
}
Emulated code:
float nonHelperLayer = gl_HelperInvocation ? 0.0 : layer;
float lH = abs(dFdxFine(nonHelperLayer));
float lV = abs(dFdyFine(nonHelperLayer));
float lD = abs(dFdxFine(lV));
float isHelperDiffH = abs(dFdxFine(float(gl_HelperInvocation)));
bool isNonHelperH = isHelperDiffH > 0.5;
float isHelperDiffV = abs(dFdyFine(float(gl_HelperInvocation)));
bool isNonHelperV = isHelperDiffV > 0.5;
if (gl_HelperInvocation)
{
layer = isNonHelperH ? lH : isNonHelperV ? lV : lD;
}
Both paths are supported as on nvidia devices the emulated code
misbehaves. This change therefore effectively only enables seamful cube
map emulation on Android where subgroup operations are not supported.

Vulkan: Seamful cube map emulation
In GLSL, a cube texture is sampled with one of textureCube* functions.
This function takes a 3D coordinate which is a vector from the center of
the cube and identifies a direction to sample from. GLES2.0 has the
following table that translates this 3D coordinate (Rx, Ry, Rz) to a
face and ST coordinates within that face. This table can be found in
Section 3.7.5 (Cube Map Texture Selection).
A compiler pass is implemented in ANGLE that replaces samplerCube
declarations with a sampler2DArray. The textureCube* functions are
replaced with the corresponding texture* functions with the translated
coordinates according to that table.
Gradients provided to textureCubeGrad are translated using the same
formulae, which is not precise but the spec specifies this projection to
be implementation dependent.
Helper invocations enabled through WQM (whole quad mode) cause a
nuisance in that the extrapolated varyings used as coordinates in a
textureCube call could have a different major axis (and therefore face)
from the non-helper invocations that lie within the geometry.
subgroupQuadSwap* operations are used in conjunction with
gl_HelperInvocation to make sure the helper threads calculate texture
UVs in the same face as the non-helper invocations.

Vulkan: Rework layout block storage conversion
Previously, a pass over the shader was made, converting shared and
packed interface blocks with block storage to std140. This resulted in
link success between interface blocks with different storage as they
were all translated to std140.
With this change, this pass is removed. The link step proceeds with the
block storage specifiers as seen by GLES, and only upon Vulkan GLSL
shader generation "shared" and "packed" are converted to std140.

Vulkan: Implement EXT_draw_buffers
In GLES, color attachments are referenced by their indices. These
indices match between the API and GLSL. For example, if a shader has:
layout(location=0) out color;
layout(location=3) out roughness;
Then GLES would bind and enable GL_COLOR_ATTACHMENT0 and
GL_COLOR_ATTACHMENT3.
In Vulkan, the framebuffer object and the corresponding renderpass
define the color attachments, and they don't allow gaps in color
attachments as GLES does. A render subpass creates the mapping between
the color attachments as defined in the framebuffer and the attachments
used by the shader (with possible gaps).
This change packs the enabled GL color attachments for the sake of the
framebuffer, and sets the subpass up in such a way that the shaders
continue to use the same color output indices as GLES.
In the example above, we have the attachment indices as follows:
Status | GLES | GLSL | RenderPass | Subpass
enabled 0 0 0 0
disabled 1 - VK_ATTACHMENT_UNUSED
disabled 2 - VK_ATTACHMENT_UNUSED
enabled 3 3 1 1
That is, the array of color attachments in the Vulkan
framebuffer/renderpass is:
[0] = GL color attachment 0
[1] = GL color attachment 3
And the array of color attachment references in the Vulkan render
subpass is:
[0] = 0 (index 0 of the renderpass attachment array)
[1] = VK_ATTACHMENT_UNUSED
[2] = VK_ATTACHMENT_UNUSED
[3] = 1 (index 1 of the renderpass attachment array)

Vulkan: Implement shader compilation.
This hooks up the Vulkan GLSL, decorated with locations, to glslang,
and then pipes the SPIRV back to the Program implementation for later
use when making pipelines to run draw calls.
The program compilation tests work now, but don't really test
anything other than not generating Vulkan validation layer errors
during compilation and shader object generation.
