8f6df770ce CompilerMSL map many GLSL functions to MSL functions.
Add bool members is_read and is_written to SPIRType::Image.
Output correct texture read/write access by marking whether textures
are read from and written to by the shader.

expression using MSL get_width() & get_height() functions.

b2c2e6483b Analyze parameter preservation for functions.
This is kinda tricky, because if we only conditionally write to a
function parameter variable it is implicitly preserved in SPIR-V, so we must force
an in qualifier on the parameter to get the same behavior in GLSL.

fadaec205b Improvements to legacy GLSL output.
- By default, emit uniform structs for UBOs, like push constant.
- Forward transpose information,
  and optimize transpose(matrix) * vector to vector * matrix.

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.

The details here get quite hairy, and it's not complete as not all
functionality is implemented in glslang yet.

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.

ed98a8ec86 Begin implementing parameter remapping for combined image sampler.
The basic idea here is that all functions will have a list of which
combinations of parameters will be combined inside the function.
The caller will then know which combined samplers must be provided to
the callee in order to satisfy it.

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.

36a0b63f28 Fix various corner cases with expression dependencies.
There was a potential problem if variables were invalidated and SPIR-V
read expressions which depended on other expression which in turn depended on the
invalidated variable.

Also fixes issue where variables were considered immutable if they were
forwardable. This allowed some incorrect optimizations to slip through.

5f629276a7 Use Boolean instead of Bool.
Xlib.h header uses a very ugly define for Bool which conflicts with
SPIRV-Cross.

The hassle free solution is to use Boolean instead.

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.
