aac6885950 GLSL: Be more aggressive about using type_alias.
To facilitate an improved linking-by-name use case for older GL,
we will be more aggressive about merging struct definitions, even for
rather unrelated cases where we don't strictly need to use type aliases.

18e24c3ca2 Reflection: Emit reflection information for array size literalness.
If not literal, check specialization_constant entries for "variable_id"
to link up ID with spec constant values. This maps directly to C++ API.

333980ae91 Refactor into stronger types in public API.
Some fallout where internal functions are using stronger types.
Overkill to move everything over to strong types right now, but perhaps
move over to it slowly over time.

96492648d4 MSL: Fix struct declaration order with complex type aliases.
MSL generally emits the aliases, which means we cannot always place the
master type first, unlike GLSL and HLSL. The logic fix is just to
reorder after we have tagged types with packing information, rather than
doing it in the parser fixup.

a489ba7fd1 Reduce pressure on global allocation.
- Replace ostringstream with custom implementation.
  ~30% performance uplift on vector-shuffle-oom test.
  Allocations are measurably reduced in Valgrind.

- Replace std::vector with SmallVector.
  Classic malloc optimization, small vectors are backed by inline data.
  ~ 7-8% gain on vector-shuffle-oom on GCC 8 on Linux.

- Use an object pool for IVariant type.
  We generally allocate a lot of SPIR* objects. We can amortize these
  allocations neatly by pooling them.

- ~15% overall uplift on ./test_shaders.py --iterations 10000 shaders/.

9b92e68d71 Add an option to override the namespace used for spirv_cross.
This is a pragmatic trick to avoid symbol collision where a project
links against SPIRV-Cross statically, while linking to other projects
which also use SPIRV-Cross statically. We can end up with very awkward
symbol collisions which can resolve themselves silently because
SPIRV-Cross is pulled in as necessary. To fix this, we must use
different symbols and embed two copies of SPIRV-Cross in this scenario,
now with different namespaces, which in turn leads to different symbols.

825ff4af7e Replace locale handling.
We were using std::locale::global() to force a C locale which is not
safe when SPIRV-Cross is used in a multi-threaded environment.

To fix this, we could tap into various per-platform specific locale
handling to get safe thread-local locales, but since locales only affect
the decimal point in floats, we simply query the locale instead and do
the necessary radix replacement ourselves, without touching the locale.

This should be much safer and cleaner than the alternative.

d2cc43e667 Fix edge case where opaque types can be declared on stack.
In the bizarre case where the ID of a loaded opaque type aliased with a
literal which was used as part of another texturing instruction, we
could end up with a case where domination analysis assumed the loaded
opaque type needed to be moved to a different scope.

Fix the issue by never doing dominance analysis for opaque temporaries,
and be more robust when analyzing texturing instructions.

Also make sure reflection output is deterministic.
This patch slightly alterered output for some unknown reason, but it came from an
unordered_map, so it's fine.

b629878f45 Make meta a hashmap.
A flat array was consuming way too much memory and was far too slow to
initialize properly with a very large ID bound (8 million IDs, showed up as #1 hotspot in perf).

Meta struct does not have to be in-order as we never iterate over it in
a meaningful way, so using a hashmap here is reasonable. Very few IDs
should need decorations or meta-data, so this should also be a quite
decent memory save.

For the pathological case, a 6x uplift was observed.

5bcf02f7c9 Hoist out parsing module from spirv_cross::Compiler.
This is a large refactor which splits out the SPIR-V parser from
Compiler and moves it into its more appropriately named Parser module.

The Parser is responsible for building a ParsedIR structure which is
then consumed by one or more compilers.

Compiler can take a ParsedIR by value or move reference. This should
allow for optimal case for both multiple compilations and single
compilation scenarios.
