Handle exponential explosion of code-gen during first phase of compile.
...
Certain patterns with OpVectorShuffle (and probably others) will cascade
to so large, that they can cause OOM. After we have observed
force_recompile, don't spend unnecessary memory emitting code which will
never be used.

Analyze the CFG for temporaries as well.
...
Normally, temporary declaration must dominate any use of it,
so we generally did not need to analyze the CFG for these variables,
but there is an edge case where you have an inliner doing:
do {
create_temporary;
break;
} while(0);
use_temporary;
The inside of the loop dominates the outer scope, but we cannot emit
code like this in GLSL, so make sure we hoist these temporaries outside
the "loop".

Always make a copy when handling OpCompositeInsert
...
The modified object might not be mutable (e.g. shader input).
Added a test for the case when this happens.

Support emitting SPIR-V type declarations tuned for specified SPIR-V objects.
...
CompilerGLSL type_to_glsl() and image_type_glsl() functions support optional object ID.
Add SPIRType::Image::access member to support SPIR-V OpTypeImage access qualifier.
Remove SPIRType::Image::is_read and ::is_written members.
Use DecorationNonReadable and DecorationNonWritable to mark read/write access for image variables.
CompilerMSL emit access qualifiers per image variable, instead of per image type.
CompilerGLSL and CompilerHLSL behaviour is unchanged.

CompilerMSL map many GLSL functions to MSL functions.
...
Add bool members is_read and is_written to SPIRType::Image.
Output correct texture read/write access by marking whether textures
are read from and written to by the shader.
Override bitcast_glsl_op() to use Metal as_type<type> functions.
Add implementations of SPIR-V functions inverse(), degrees() & radians().
Map inverseSqrt() to rsqrt().
Map roundEven() to rint().
GLSL functions imageSize() and textureSize() map to equivalent
expression using MSL get_width() & get_height() functions.
Map several SPIR-V integer bitfield functions to MSL equivalents.
Map SPIR-V atomic functions to MSL equivalents.
Map texture packing and unpacking functions to MSL equivalents.
Refactor existing, and add new, image query functions.
Reorganize header lines into includes and pragmas.
Simplify type_to_glsl() logic.
Add MSL test case vert/functions.vert for added function implementations.
Add MSL test case comp/atomic.comp for added function implementations.
test_shaders.py use macOS compilation for MSL shader compilation validations.

Prefer plain texture2D in legacy es vertex shaders
...
WebGL supports lod texture funcs only in fragment
shaders but SPIR-V supports only lod texture funcs
in vertex shaders. This reverts calls which were
forced (infered from using a 0 constant) to use
an lod to plain calls in vertex shaders when
using legacy es.
