James Price a5d73ce965 transform/shader_io: Generate a wrapper function 
This is a major reworking of this transform. The old transform code
was getting unwieldy, with part of the complication coming from the
handling of multiple return statements. By generating a wrapper
function instead, we can avoid a lot of this complexity.

The original entry point function is stripped of all shader IO
attributes (as well as `stage` and `workgroup_size`), but the body is
left unmodified. A new entry point wrapper function is introduced
which calls the original function, packing/unpacking the shader inputs
as necessary, and propagates the result to the corresponding shader
outputs.

The new code has been refactored to use a state object with the
different parts of the transform split into separate functions, which
makes it much more manageable.

James Price 5c61d6d12c msl: Fold &* when converting module-scope vars 
This transform was previously converting this code:
```
var<private> v : f32;
fn foo() {
  bar(&v);
}
```

into this:
```
fn foo(vp : ptr<private, f32>) {
  bar(&*vp); // Invalid, since ptr args must be &ident
}
```

Ben Clayton 9569e2c790 writer/msl: Emit helper functions for atomicCompareExchangeWeak 
By generating a helper function for these, we can keep the atomic expression pre-statement-free. This can help prevent for-loops from being transformed into while loops.

Ben Clayton e6d171ac66 writer/hlsl: Implement atomics 
Storage buffers are emitted as `ByteAddressBuffer`s in HLSL, so we have to jump through hoops to support atomic ops on storage buffer atomics.
Workgroup atomics are far more conventional, but very little code can be shared between these two code paths.
