db55d474f9 MSL: Do not declare complex composite array in main for non-inlined.
Need to consider that complex composite arrays may be used in leaf
functions, and avoid the MSL library link fix unless everything is
nicely inlined.

d92de00cc1 Rewrite how IDs are iterated over.
This is a fairly fundamental change on how IDs are handled.
It serves many purposes:

- Improve performance. We only need to iterate over IDs which are
  relevant at any one time.
- Makes sure we iterate through IDs in SPIR-V module declaration order
  rather than ID space. IDs don't have to be monotonically increasing,
  which was an assumption SPIRV-Cross used to have. It has apparently
  never been a problem until now.
- Support LUTs of structs. We do this by interleaving declaration of
  constants and struct types in SPIR-V module order.

To support this, the ParsedIR interface needed to change slightly.
Before setting any ID with variant_set<T> we let ParsedIR know
that an ID with a specific type has been added. The surface for change
should be minimal.

ParsedIR will maintain a per-type list of IDs which the cross-compiler
will need to consider for later.

Instead of looping over ir.ids[] (which can be extremely large), we loop
over types now, using:

ir.for_each_typed_id<SPIRVariable>([&](uint32_t id, SPIRVariable &var) {
	handle_variable(var);
});

Now we make sure that we're never looking at irrelevant types.

b114889102 Only declare typed initializer list for non-array types.
Also, cleanup now redundant constant_expression virtualization for MSL.

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.

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.
