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.

6ae838c192 Fix legacy GLSL output with gl_FragData.
If the source GLSL file accessed gl_FragData, we got double up
with array access, giving invalid GLSL.

7693656d68 Change variable names beginning with gl_ in GLSL
Using old-school GLSL as input containing code ala
"gl_FragColor = whatever" resulted in illegal
declarations ala "out vec4 gl_FragColor;".

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.

4739d16e98 Remove workaround for overly conservative memory barriers.
This is now fixed in ESSL 3.10 backend of glslang, so we can remove the old workaround
of dropping full memory barriers.

Also fixes unrelated issue which newer glslang detects.

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.
