2abdc135c3 Declare undefined values up front.
They might potentially be used as part of OpStore in the SPIRV-Tools
inliner in some cases.

Implement these as declared variables but without any initializer.

5d4bb687bc Support arrays which have spec constant size.
The size of an array can be a specialization constant or a spec constant
op. This complicates things quite a lot.

Reflection becomes very painful in the presence of expressions instead
of literals so add a new array which expresses this.

It is unlikely that we will need to do accurate reflection of interface
types which have specialization constant size.

SSBOs and UBOs will for now throw exception if a dynamic size is used since it
is very difficult to know the real size.

4d4e6d7a41 Document variable type remap interface a bit more.
Fix some minor missing pieces from C++.
Type remapping like this doesn't seem to fit MSL backend so well, as it
does a lot of remapping internally on its own.

Type name remapping, really is for fringe extension cases in GLSL which
aren't yet supported in SPIR-V.

042475e88e Add support for multiple entry points.
- Only consider I/O variables if part of OpEntryPoint.
- Keep a safe fallback if #entry-points is 1 to avoid potentially
  breaking previously working shaders.

d5dc5f3f1c Fix issue with new glslang behavior for samplers as parameters.

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.

6aa2007cba Deal better with OpName and OpMemberName which alias.
OpName is only for debug information, so we must be very careful that
we do not reuse the same name for different variables.

This was previously done for local variables, but this commit extends
this to global variables as well.

78e7615af6 Do not use flexible member arrays in C++.
This is supported as compiler extensions, but we can be standards
compliant here, so use the classic workaround of having a single entry
array at the end of the structs instead.

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.
