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.

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;".

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.

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.

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.

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.

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.

Do not rely on OpName when finding OpTypeStruct aliases.

SPIR-V can stamp out multiple variants of the same types to deal with
different offsets, layouts, array strides and so on in buffer blocks.

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.
