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.

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.

5c24d99ff2 Add distinction between type_id and base_type_id in resource interface. 
type_id was not intuitive and did not allow for parsing array sizes of
variables.

Expose another member, base_type_id which will provide the base type
suitable for parsing metadata such as decorations and type_id will now
point to the actual type which includes full type information such as
arrays and so on.

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.

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.
