b46910e9f5 Access chain into packed vectors as arrays.
Cleaner and should be more compatible with storing to packed vector
elements.

Fix CompositeExtract bug with packed vectors on MSL.

d8d2da9d8d CompilerMSL allow swizzle of packed_float3 vectors by unpacking to float3.
Pass packed indicator back through OpAccessChain and OpLoad.
Unpack packed vector before applying swizzle.
Add packed swizzle test.

1c18078811 Enhancements to MSL compute and entry point naming.
Support Workgroup (threadgroup) variables.
Mark if SPIRConstant is used as an array length, since it cannot be specialized.
Resolve specialized array length constants.
Support passing an array to MSL function.
Support emitting GLSL array assignments in MSL via an array copy function.
Support for memory and control barriers.
Struct packing enhancements, including packing nested structs.
Enhancements to replacing illegal MSL variable and function names.
Add Compiler::get_entry_point_name_map() function to retrieve entry point renamings.
Remove CompilerGLSL::clean_func_name() as obsolete.
Fixes to types in bitcast MSL functions.
Add Variant::get_id() member function.

f591bc0d4a CompilerMSL enhancements.
Support BuiltInFragDepth.
Emit interface block for StorageClassUniformConstant.
Throw exception when output or fragment input structs contain matrix or array.
Dynamically created interface structs sorted by location number instead of alphabetically.
Add Compiler::is_array() function.

de33d89074 Add explicit in/out locations everywhere.
Needed for newer glslang. With Vulkan semantics for SPIR-V, all
locations must be explicitly defined.

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.

5550c87b1f CompilerMSL options access and UBO alignment test case.
CompilerMSL accesses options using same design pattern as CompilerGLSL and CompilerHLSL.
CompilerMSL support setting VA & rez binding specs via either constructor or compile() method overload.
CompilerMSL support single UBO packing and padding in single pass.
spriv_cross app (main.cpp) supports turning off UBO packing and padding via command line option.
Add MSL UBO alignment test shader.

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.
