41eb5c43b5 MSL: Fix OpAtomicIIncrement and OpAtomicIDecrement.
We were passing a constant '1' to `emit_atomic_func_op()`--which caused
us to refer to SPIR-V value `%1`, which is almost certainly not what we
want! What we really want is to add/subtract the literal constant '1'
to/from the memory location.

6757ef8512 Use bitcast_to_builtin_load() instead of hacking to_expression().
This only affects the builtin when it is used, and not when it's passed
to a function. It's a lot cleaner than the way I was doing it before.

Remove the `to_expression()` hack.

f7dad9da66 MSL: Cast uses of builtin vectors to their declared SPIR-V type.
In SPIR-V, builtin integral vectors can be either signed or unsigned,
but in MSL they're always unsigned. Unfortunately, the MSL spec forbids
implicit conversions between vector types--even if the corresponding
scalar types would implicitly convert. If you try, the result is a
cryptic error message such as:

```
program_source:37:60: error: cannot convert between vector values of different size ('int4' (aka 'vector_int4') and 'vector_uint4' (vector of 4 'unsigned int' values))
            float4 r3 = as_type<float4>((as_type<int4>(r0) * gl_LocalInvocationID.xyyy) + as_type<int4>(r2));
                                         ~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~
```

Therefore, uses of these builtins must be explicitly cast, since the
rest of the binary likely assumes that the builtin is of its declared
type.

680ef9d773 MSL: Correct number of words to skip in OpImageWrite.
The length field in `Instruction` doesn't include the initial
opcode/length word. We only need to skip three words instead of four.

9fbe39c9c0 MSL: Emit spvTexelBufferCoord() on ImageWrite to a Buffer as well.
This is necessary to get the coordinates to give to the texture's
`write()` method.

87de951105 MSL: Fix naming issue of aliased global variables.
When the name of an alias global variable collides with a global
declaration, MSL would emit inconsistent names, sometimes with the
naming fix, sometimes without, because names were being tracked in two
separate meta blocks. Fix this by always redirecting parameter naming to
the original base variable as necessary.

146ea76f52 Add test shader for subgroup.
Update SPIRV-Tools/glslang commits.
Use vulkan1.1 environment for testing.
Found new "errors" in SPIRV-Tools, so disable validation on those shaders
for now.
