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.

and also fixes a few bugs in GLSL backend with array-of-arrays.

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.

5ad4340976 Workaround case with identical structs but different types. 
With the current workarounds for SSBO type aliasing, we have no choice
but to look at OpName in order to figure this out 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.

f05373bdd1 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.

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.

45ad58a903 Implement more correct integer op handling. 
In some cases we need to bitcast when dealing with int vs. uint.
SPIR-V allows inputs to be of different integer signedness, so we need
to deal with this somehow.

Add testing system to test SPIR-V assembly.
For now, test all possible combination for all major cases.

 - IAdd (which doesn't care about input type as long as they're equal)
 - SDiv/UDiv operations which case about input type.
 - Arith/Logical right shifts.
 - IEqual to test outputs to bvec, which shouldn't get output cast. Also
   tests casting in function-like calls.

59d6898fd0 Add a CMakeLists.txt file for use by cmake, ctest 
This enables out-of-tree builds, and the use of other build tools.

This will not overwrite Makefile if you are building in the
source tree.  To use makefiles generated from CMake, you must
build out of the source tree.

Usage: If SPIRV-Cross source is in $SPIRV_CROSS_ROOT, then to
build with ninja in a different directory:

   cmake -G Ninja $SPIRV_CROSS_ROOT
   ninja

   # Run tests, if enabled
   ctest

Tests will be enabled if you have python3.

so workaround to verify that the other cases at least still work as expected.
