Translator: Limit private variable size to 64KB
This is indirectly fixing an issue where passing large arrays in SPIR-V
such that an internal cast is needed (such as array inside interface
block copied to local varaible) causes an overflow of the instruction
length limit (in the absence of OpCopyLogical).
By limiting the size of private variables to 32KB, this limitation is
indirectly enforced. It was observed that all the test shaders added in
this CL fail on the Nvidia OpenGL drivers, so such a limit seems to be
reasonble.

Translator: Clean up the compile flag passing interface
Historically, compile flags were sent to the translator as a bitmask.
Recently, we were getting close to running out of bits. Additionally,
direct-to-metal work had started to introduce constants to be passed to
the translator, which were misplaced in ShBuiltInResources and Caps.
Recent work on Pixel Local Storage adds even more constants, aggravating
the situation.
In this change, the interface to passing compile flags is reworked. A
struct is passed (instead of a bitmask) that has one bit for each flag.
This can be indefinitely extended. Additionally, the constants needed
by metal and PLS are also placed in this struct. In turn, the backends
can set these options directly, and don't have to hack them into Caps to
further get hacked into ShBuiltInResources.

Translator: Simplify RecordConstantPrecision
Just before ESSL output, this transformation made some constants
specified through temp variables such that their precision can be
specified. This was done in cases where the precision actually affected
the expression being evaluated.
This transformation is simplified by declaring constants more
conservatively as variables, and not stringently attempting to identify
whether that's necessary. This is still not done in trivial cases.
This change is in preparation for another change that overhauls
precision propagation through the nodes. This change removes all
references to TIntermTyped::getPrecision() outside the precision
promotion code itself.

Standardize copyright notices to project style
For all "ANGLE Project" copyrights, standardize to the format specified
by the style guide. Changes:
- "Copyright (c)" and "Copyright(c)" changed to just "Copyright".
- Removed the second half of date ranges ("Y1Y1-Y2Y2"->"Y1Y1").
- Fixed a small number of files that had no copyright date using the
initial commit year from the version control history.
- Fixed one instance of copyright being "The ANGLE Project" rather than
"The ANGLE Project Authors"
These changes are applied both to the copyright of source file, and
where applicable to copyright statements that are generated by
templates.

Prefix user-defined names in GLSL output
Now user-defined names are prefixed by _u in GLSL output in case name
hashing is not on. Internal names such as names of temporary variables
created in AST transformations are written out as such.
This makes handling of internal function names and internal variable
names consistent. It also removes the possibility of name conflicts
between user-defined names and internal names in case name hashing is
not on. In the same vein, it makes it safe to use GLSL reserved words
that are not reserved in ESSL as variable names in case name hashing
is not on.
This also makes the GLSL output more consistent with how names are
handled in HLSL output. Name hashing code is shared between
VariableInfo and OutputGLSLBase to ensure names are handled
consistently in both. The name that's used in the shader source for a
given interface variable is written out to ShaderVariable::mappedName.
An exception needs to be made for identifiers close to the length
limit, since adding any prefix would take them over the limit. But
they can be just written out as such, since we don't have any builtins
or ANGLE internal variables that have as long names and could create a
conflict.

translator: Scope all classes with "sh".
I was seeing an odd problem with our PoolAlloc conflicting with the
glslang/Vulkan TIntermNode, so the fix was to move everything to a
separate namespace.
The bison grammars are also regenerated. No functional changes.

Prefix internal names in GLSL output
Prefixing internal names will avoid clashes with user-defined names.
We use prefix webgl_angle_ so that the internal names are both
reserved in WebGL on one hand and clearly separated from hashed names
starting with just webgl_ on the other hand.

Add a helper class for compiler string matching tests
The MatchOutputCodeTest class makes it easier to implement tests that
do string matching on compiler output. Inheriting test classes set the
compiler settings, tests then call compile() with the shader string
and can call foundInCode() to check if the output code contains a
given string.
Various compiler unit tests that already did string matching are
refactored to make use of this new helper class. Some tests now use
SH_GLES3_SPEC instead of SH_GLES2_SPEC - this should not have a
significant impact on test coverage.
Some compileTestShader function variants that are now unused can be
removed from the code.
