1fb27b4cda Add support for 8- and 16-bit types to GLSL and MSL.
In GLSL, 8-bit types require GL_EXT_shader_8bit_storage. 16-bit types
can use either GL_AMD_gpu_shader_int16/GL_AMD_gpu_shader_half_float or
GL_EXT_shader_16bit_storage.

9b4defe202 CompilerMSL support matrices & arrays in stage-in & stage-out.
Support flattening StorageOutput & StorageInput matrices and arrays.
No longer move matrix & array inputs to separate buffer.
Add separate SPIRFunction::fixup_statements_in & SPIRFunction::fixup_statements_out
instead of just  SPIRFunction::fixup_statements.
Emit SPIRFunction::fixup_statements at beginning of functions.
CompilerMSL track vars_needing_early_declaration.
Pass global output variables as variables to functions that access them.
Sort input structs by location, same as output structs.
Emit struct declarations in order output, input, uniforms.
Regenerate reference shaders to new formats defined by above.

991b655c72 Declare OpSpecConstantOp up-front on relevant targets.
Required, since spec constants can include results from constant ops.

1f83856366 CompilerMSL add support for MSL specialization function constants.
CompilerMSL add emit_custom_functions() function.
CompilerMSL restrict use of as_type<> cast to necessary conditions.
CompilerMSL refactor get_declared_struct_member_size() and
get_declared_struct_member_alignment() functions, and remove
unnecessary get_declared_type_size() functions.
Add test shaders-msl/vulkan/frag/spec-constant.vk.frag.

192bdc9516 CompilerMSL elide unused builtins from entry function input and output structs.

Update test reference shaders that included unused builtins.

f9f87ca391 CompilerMSL output [[point_size]] attribute for BuiltInPointSize member by default.
CompilerMSL::Options::is_rendering_points defaults to true.

be4cb17a14 Enhance MSL testing and add numerous MSL test cases.
Add to suite of MSL tests and references any existing GLSL tests
that successfully convert GLSL->SPIRV->MSL and compile as MSL.
test_shaders_helper() ignores hidden files that start with '.',
to avoid accidentally finding hidden OSX files such as .DS_Store.
Use xcrun to compile MSL shaders instead of hard-coded path to Metal compiler.
Wrap calls to xcrun in exception handling to ignore if Xcode not installed.
For MSL tests, move call to validate_shader_msl() to after call to
regression_check() to allow a converted MSL shader to be saved for
manual review even if it doesn't successfully compile as MSL.
