3fe57d3798 Do not use SmallVector as input type in public interfaces.
This is an API break, which we need to be careful with.
Handing out SmallVectors is easier since the interface is basically the
same.

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.

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.

c172a3507c Add support for custom C++ interface names.
Mostly useful for baking several shaders into the same binary without
getting symbol collisions.

168e46fdf9 Use std::array in C++ backend.
Deals better with composite construction in C++
and also fixes a few bugs in GLSL backend with array-of-arrays.

2eb6037ff3 Remove type aliases when emitting buffer blocks in C++.
C++ emits separate structs, which we must always emit properly.

4b8ed53974 Add Clang format.
Reformats the entire codebase. Better to do it now than later.

Adds .clang-format and a convenience script format_all.sh which formats
everything automatically.
