b2c2e6483b Analyze parameter preservation for functions. 
This is kinda tricky, because if we only conditionally write to a
function parameter variable it is implicitly preserved in SPIR-V, so we must force
an in qualifier on the parameter to get the same behavior in GLSL.

ed04c95b08 Implement flattening of row major matrix indexing 
To extract a column from row-major matrix, we need to do a strided load one
component at a time. In this case flattened_access_chain_offset still returns
the offset to the first element, but the stride is equal to matrix stride
instead of vector stride.

For this to work, we need to pass matrix stride (and transpose flag) through,
similar to how matrix flattening works.

Additionally slightly clean up recursive flattened_access_chain structure -
specifically, instead of deciding mid-traversal that we need matrix stride
information, we can just pass the matrix stride through - for access chains
that end in matrix/vector this gets us what we need, and for access chains
that end in structs the flattened_access_chain_struct code will recompute
correct stride/transposition data to pass through further.

62b27f1d81 Implement access chain flattening support for row major matrices 
We currently only support access chains that end in a matrix by propagating
"needs transpose" flag upstream which flips the matrix multiplication order.

It's possible to support indexed extraction as well, however it would have to
generate code like this:

    vec4 row = vec4(UBO[0].y, UBO[1].y, UBO[2].y, UBO[3].y);

for a column equivalent of:

    vec4 row = UBO[1];

It is definitely possible to do so but it requires signaling the vector output
that it needs to switch to per-component extraction which is a bit more trouble
than this is worth for now.

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.

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.
