c51e5b7911 MSL: Add a setting to capture vertex shader output to a buffer. 
This will be necessary to support transform feedback, as well as
tessellation shaders.

ef0b1fc841 Move assertions after the check for equal types. 
`bitcast_glsl_op()` is sometimes called for `Boolean` types, e.g. for
specialization constants. We don't want the assert to trip if this is
going to be a no-op anyway.

2ed171e525 GLSL/MSL: Implement 8-bit part of VK_KHR_shader_float16_int8. 
Storage was in place already, so mostly just dealing with bitcasts and
constants.

Simplies some of the bitcasting logic, and this exposed some bugs in the
implementation. Refactor to use correct width integers with explicit bitcast opcodes.

217eb5b5f9 MSL: Add a preliminary check for bad arrays of structs. 
ArrayStride can be larger than the declared struct size.
We have no obvious solution for now, but warn about it in the MSL output
for the time being.

8c632da461 MSL: Use correct alignment rule for whole structs. 
Structs are aligned as you would expect in MSL (maximum member
alignment), and it is not minimum 16 bytes like in std140.

Also rename the dummy "pad" members to a reserved naming scheme.

437fc87a89 MSL: Deal with resource name aliasing. 
Apparently we didn't use those yet. MSL seems to be able to alias struct
types and variable types to a degree, so that's why it has escaped
testing until now.

Still a bit buggy, since we cannot deduce between float2[] and

664df22d12 MSL: Fix passing a sampled image to a function. 
In the past, SPIRV-Cross threw an error in this case because it couldn't
work out which swizzle from the auxiliary buffer needs to be passed.
Now, we pass the swizzle around with the texture object, like a combined
image-sampler and its associated sampler.

b8033d7525 MSL: Add option to pad fragment outputs. 
If not enough components are provided in the shader,
the shader MSL compiler throws an error rather than make components
undefined. This hurts portability, so we need to add explicit padding
here.

7ee04936ac MSL: Fix case where we pass arrays to functions by value. 
MSL does not support value semantics for arrays (sigh), so we need to
force constant references and deal with copies if we have a different
address space than what we end up guessing.
