Add shader translator support for OVR_multiview
The OVR_multiview and OVR_multiview2 extensions add gl_ViewID_OVR to
shaders. gl_ViewID_OVR can be translated either as is in GLSL output
or as a uniform by setting the SH_TRANSLATE_VIEWID_OVR_AS_UNIFORM
compiler flag.
If WebGL output is selected, the shaders will be validated according
to proposed rules in the WEBGL_multiview spec.

translator: remove code related to for-loop unrolling
For loop unrolling is not used and causes the translator fuzzer to find
a hang when unrolling tons of nested loops (duh).
Also remove MMap.h which was unused.

translator: Put ShaderLang APIs in "sh" namespace.
Working with glslang in Vulkan means we are static linking libANGLE
with functions that have the same name as our translator APIs. We
can fix this by scoping our APIs. We don't need to scope the types
of the file, since they don't conflict.
This will require a follow-up patch to remove the unscoped APIs
once we switch over Chromium.
We also scope TCompiler and some related classes to avoid multiply
defined link errors with glslang.

Remove SH_TIMING_RESTRICTIONS compiler flag
The timing restrictions code is not in use and not updated for ESSL3,
so it is better to remove it to make refactoring the AST easier.
It can also be argued that perfect prevention of shader timing attacks
is not feasible due to factors that are not under control of ANGLE,
such as fixed function color compression in GPUs. Such color
compression may make the use of texture bandwidth and thus performance
dependent on the content of a texture regardless of whether a
compressed format is chosen through the API.
SH_DEPENDENCY_GRAPH flag that could only be active together with the
timing restrictions flag is also removed, along with all the code that
was supporting it. The newer CallDAG code is used for different
purposes and is kept.

Disallow multiple locations on output variables

location qualifier may appear at most once within a declaration.
Enforce this rule when parsing shaders.
Also set max draw buffers to 8 when compiling GLSL ES >= 3.00 in the

A separate macro ES3_1_ONLY is added so that some tokens are limited

Redesign samplers in shaders on D3D11
Translation of samplers to HLSL on D3D11 is changed as follows:
Instead of passing around HLSL sampler and HLSL texture references in
shaders, all references to ESSL samplers are converted to constant
indices within the shader body. Each ESSL sampler is identified by an
unique index. In the code generated to implement ESSL texture functions,
these indices are used to index arrays of HLSL samplers and HLSL
textures to get the sampler and texture to use.
HLSL textures and samplers are grouped into arrays by their types. Each
unique combination of a HLSL texture type + HLSL sampler type gets its
own array. To convert a unique sampler index to an index to one of these
arrays, a constant offset is applied. In the most common case of a 2D
texture and a regular (non-comparison) sampler, the index offset is
always zero and is omitted.
The end goal of this refactoring is to make adding extra metadata for
samplers easier. The unique sampler index can be used in follow-up
changes to index an array of metadata passed in uniforms, which can
contain such things as the base level of the texture.
This does not solve the issues with samplers in structs.
The interface from the point of view of libANGLE is still exactly the
same, the only thing that changes is how samplers are handled inside the
shader.
On feature level 9_3, the D3D compiler has a bug where it can report that
the maximum sampler index is exceeded when in fact it is not. This can
happen when an array of samplers is declared in the shader. Because of
this the new approach can't be used on D3D11 feature level 9_3, but it
will continue using the old approach instead.

Don't split the file into two chunks in shader_translator
Splitting the file into two strings in shader_translator complicated
testing line/file numbering related functionality with it, since each
chunk passed to ShCompile has its own file number and line numbering.
These are exposed to the preprocessor in __FILE__ and __LINE__ predefined
macros.
Just supply the file to ShCompile in a single string. Also, since the
original motivation for splitting the string seems to have been to
exercise ShCompile with multiple strings, add a new unit test that
ensures that ShCompile handles multiple strings as expected.

Implement ES 2,3 parts of EXT_blend_func_extended for shader translation
Exposes gl_SecondaryFragColor, glSecondaryFragData[] and
gl_MaxDualSourceDrawBuffers to GLES SL 1.0.
Relaxes rules for undefined output locations for GLES SL 3.0
and exposes gl_MaxDualSourceDrawBuffers.
If the output GL context is GL ES 2.0 or 3.0:
The emulation layer is expected to turn on EXT_blend_func_extended
if the output GL context supports it.
If the output GL context is GL:
The emulation layer is expected to turn on EXT_blend_func_extended
if the output GL context supports ARB_blend_func_extended or if GL
context is 3.2 or later.
If the source shader spec is GLES SL 2.0: The emulation layer is
expected to inspect the shader compilation output variables upon
linking. If output target is GL SL, the emulation layer should bind
color location 0, index 1 to "angle_SecondaryFragColor" if variable
"gl_SecondaryFragColorEXT" is used. Alternatively, emulation layer
should bind "angle_SecondaryFragData" to locations 0,1,2,3,..., all
color index 1, if "gl_SecondaryFragData" array is used.
(The caller can not bind the locations or specify output variables.)
If the source shader spec is GLES SL 3.0:
The emulation layer is expected to do location auto-resolve of the
the output variables that have undefined output locations that have
not been bound by the caller.
(The caller can not use gl_ built-ins, so nothing to do with those.)
