c51e5b7911 MSL: Add a setting to capture vertex shader output to a buffer.
This will be necessary to support transform feedback, as well as
tessellation shaders.

912fde95f1 MSL: Use correct size for structs.

217eb5b5f9 MSL: Add a preliminary check for bad arrays of structs.
ArrayStride can be larger than the declared struct size.
We have no obvious solution for now, but warn about it in the MSL output
for the time being.

8c632da461 MSL: Use correct alignment rule for whole structs.
Structs are aligned as you would expect in MSL (maximum member
alignment), and it is not minimum 16 bytes like in std140.

Also rename the dummy "pad" members to a reserved naming scheme.

f500d2f70c MSL: Hoist fixup hooks in entry_point_args() out of the compile loop.
Otherwise, in the event of a forced recompile, we could end up adding
them twice.

15b52bee48 Deal with packing/unpacking on store.
Still a bit buggy, since we cannot deduce between float2[] and
packed_float2. Need a deeper refactor to plumb this through ...

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.

480acdad18 Deal with OpSpecConstantOp used as array size.
When trying to validate buffer sizes, we usually need to bail out when
using SpecConstantOps, but for some very specific cases where we allow
unsized arrays currently, we can safely allow "unknown" sized arrays as
well.

This is probably the best we can do, when we have even more difficult
cases than this, we throw a more sensible error message.

af75ef005f Update glslang and SPIRV-Tools.
A lot of changes in spirv-opt output.
Some new invalid SPIR-V was found but most of them were not significant
for SPIRV-Cross, so just marked them as invalid.
