Add support for non-float mix
The non-float variations of the mix builtin were conditioned to desktop
GLSL, but they are present in ESSL 3.1+. This change also implements
constant folding of these builtins as exercised by dEQP.

Implement SamplerVideoWEBGL for WEBGL_video_texture extension on desktop
WEBGL_video_texture is an extension that will improve uploading video frame to WebGL performance.
(https://www.khronos.org/registry/webgl/extensions/proposals/WEBGL_video_texture/)
This extension introduced a new texture type TEXTURE_VIDEO_IMAGE_WEBGL and a new sampler type
samplerVideoWEBGL to sample it.
In chromium implementation, TEXTURE_VIDEO_IMAGE_WEBGL maps to different native texture type
based on platform. On desktop, it maps to GL_TEXTURE2D(Currently supported). On Android, it
should map to GL_TEXTURE_EXTERNAL(TODO). SamplerVideoWEBGL needs to be mapped to sampler2D or
samplerExternalOES according to TEXTURE_VIDEO_IMAGE_WEBGL implementation.
This patch implements samplerVideoWEBGL in Angle to support WEBGL_video_texture on desktop. In
this case, samplerVideoWEBGL should map to sampler2D.

Implement Draw base vertex and base instance functions
This patch implements functionality of glDrawArraysInstancedBaseInstanceANGLE,
glDrawElementsInstancedBaseVertexBaseInstanceANGLE,
glMultiDrawArraysInstancedBaseInstanceANGLE,
and glMultiDrawElementsInstancedBaseVertexBaseInstanceANGLE
Workaround for OpenGL driver on Mac:
gl_VertexID on Mac with AMD GPU doesn't include baseVertex value.
So replace gl_VertexID with (gl_VertexID + angle_BaseVertex) if any.
Workaround for Vulkan GLSL:
gl_InstanceIndex on Vulkan includes baseInstance. So replace
gl_InstanceIndex with (gl_InstanceIndex - angle_BaseInstance) when
angle_BaseInstance is declared.

Avoid mangled name comparisons of 3-parameter functions
The hash values used for looking up built-ins now encode whether the
mangled name contains arrays, structs or interface blocks in its
parameters list. This is written in the most significant bit of the
hash value.
We check this bit at the start of built-in lookup and if the bit is
set we exit early. After that we know that the lookup name doesn't
contain array, struct or interface block parameters.
When we find a hash that matches a hash of a built-in function, we now
know 3 things:
1) the length of the mangled name matches
2) the open parentheses in the mangled name matches
3) the lookup doesn't contain array, struct or block parameters.
Additionally, we have an if statement checking whether the function
name matches. Collisions are only possible with functions that
1) have the same name
2) have the same number of parameters
With these preconditions we can check beforehand whether collisions
are possible for 3-parameter functions. If there are no collisions, we
don't need to compare the full mangled name. This is similar to what
was already being done with functions that had 0 to 2 parameters.
This reduces shader_translator binary size by around 4 KB on Windows.
Besides increased complexity, the tradeoff is that an exhaustive
search of hash values for possible 3-parameter combinations is costly,
so the gen_builtin_functions.py code generation script now takes
around one minute to run on a high-end workstation. Due to this, the
script now exits early if it detects it has already been run with the
same inputs based on a hash value stored in
builtin_symbols_hash_autogen.txt.

Rely on hash to check for some mangled name matches
When we are looking up a function with only a few parameters, we can
optimize the lookup by relying on the information encoded in the hash
value. There's often only one list of parameters with the same
function name and mangled name length that results in a matching hash,
so we don't actually need to compare the full mangled name. We can
just compare
1) the hash value of the mangled name
2) the mangled name length
3) the function name
to make sure that the mangled name matches the mangled name of the
function.
This decreases the binary size since we don't need store as many
mangled names of built-in functions. Effect on symbol lookup speed is
marginal.

Generate code for looking up built-ins
Instead of storing built-ins in a std::unordered_map, we now generate
a series of switch statements using the hash value of the look-up
string. This works similarly to earlier implementation of looking up
unmangled built-ins.
Those built-ins that need to be initialized at run-time are stored as
member variables of TSymbolTable.
This increases compiler init performance significantly, as well as
increasing compiler perf test scores around 1-2%. Binary size is
larger than before though.
