3b5968bb26 Deal with switch cases which break out of a loop. 
Need some pretty hideous ladder variable system, but high level
languages do not support breaking out of a loop. break in switch blocks
and break in loops alias each other.

7dcfed888a Use a hook to emit a local for the sample position. 
That way, we don't have to handle it specially when constructing a call.

340957a3ab Make fixup_hooks more flexible. 
No reason why it needs to return a string.
Callbacks can just do one or more statements themselves.

39bc101e82 MSL: Handle the SamplePosition builtin. 
This is somewhat tricky, because in MSL this value is obtained through a
function, `get_sample_position()`. Since the call expression is an
rvalue, it can't be passed by reference, so functions get a copy
instead.

This was the last piece preventing us from turning on sample-rate
shading support in MoltenVK.

d310060f92 MSL: Support global I/O block and struct Input/Output usage. 
Implement this by flattening outputs and unflattening inputs explicitly.
This allows us to pass down a single struct instead of dealing with the
insanity that would be passing down each flattened member separately.

Remove stage_uniforms_var_id.
Seems to be dead code. Naked uniforms do not exist in SPIR-V for Vulkan,
which this seems to have been intended for. It was also unused elsewhere.

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.
