e67f6f85a4 Defer parenthesis generation until needed.
Previously, we would generate parentheses proactively when generating
binary ops, however, this leads to uglier code and hits warnings in
compilers when used as a conditional.

9577568d56 Corrects some problems converting to compilable MSL from SPIRV. A better solution is to refactor the glsl compiler base-class so some keywords and actions can be overridden, and then the msl subclass can override them - this is a quick & dirty solution.
- adds some common macros that correct for intrinsic differences
 - adds some inline functions to adapt for GLSL terms
 - injects structure member names when the original SPV has been stripped - there is another way to use the correct temporarily assigned member name, but using m_<id> based on the inside SPV code yields metal code that more correctly maps to the original SPV opcodes/slots.

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.

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.

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.
