8f6df770ce 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.

3f74503aca 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.

4c198bbce9 Remove emission of function prototypes in MSL.
Do not emit function prototypes. If secondary functions are used,
suppress compiler -Wmissing-prototypes warnings.
Refactor Compiler::emit_function_prototype() functions to simplify.
Rename Compiler_msl::CustomFunctionHandler to OpCodePreprocessor, and
Compiler_msl::register_custom_functions() to preprocess_op_codes()
to perform more generic preprocessing.
Add space between dynamic header lines and fixed header lines.

e73e8e4f48 Add support for the BuiltInClipDistance builtin for MSL.
CompilerGLSL builtin_to_glsl() function outputs gl_ClipDistance for BuiltInClipDistance
builtin, and includes builtin code in output when handling unknown builtin code.
CompilerMSL uses type ID instead of type object where appropriate to support array types,
where type.self is not consistent with actual type ID, plus support array stride calc
even when not explicitly set by SPIR-V code.
For output consistency, CompilerMSL prefers use of standard builtin names over specified
names, and output builtins qualified with output struct while in entry function.
