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.

4b99fdd5d0 MSL: Account for components when assigning locations to varyings.
Two varyings (vertex outputs/fragment inputs) might have the same
location but be in different components--e.g. the compiler may have
packed what were two different varyings into a single varying vector.
Giving both varyings the same `[[user]]` attribute won't work--it may
yield unexpected results, or flat out fail to link. We could eventually
pack such varyings into a single vector, but that would require us to
handle the case where the varyings are different types--e.g. a `float`
and a `uint` packed into the same vector. For now, it seems most
prudent to give them unique `[[user]]` locations and let Apple's
compiler work out the best way to pack them.

ee44f6027b Changed OpTypeImage to only flag depth if the op is 1
Based on the SPIR-V spec, `Depth` is only guaranteed if the op is 1. An op of 2 may or may not be depth, which is what DXC outputs for all texture types.

Deal with various query functions which require dummy sampler.
In SPIR-V, separate images are used, but GLSL (even Vulkan GLSL)
requires combined sampler images ...

eecbeaa33d Take execution model into account for entry point methods.
SPIR-V allows names to alias if they implement different stages.
Deprecate the old interface and replace it with a new one which takes
execution modes into account.
