7eecf5a46b MSL: Support SPV_KHR_multiview. 
This is needed to support `VK_KHR_multiview`, which is in turn needed
for Vulkan 1.1 support. Unfortunately, Metal provides no native support
for this, and Apple is once again less than forthcoming, so we have to
implement it all ourselves.

Tessellation and geometry shaders are deliberately unsupported for now.
The problem is that the current implementation encodes the `ViewIndex`
as part of the `InstanceIndex`, which in the SPIR-V environment at least
only exists in the vertex shader. So we need to work out a way to pass
the view index along to the later stages.

This implementation runs vertex shaders for all views up to the highest
bit set in the view mask, even those whose bits are clear. The fragments
for the inactive views are then discarded. Avoiding this is difficult:
calculating the view indices becomes far more complicated if we can only
run for those views which are set in the mask.

ff87419607 Deal with scalar input values for distance/length/normalize. 
HLSL and MSL don't support it, so fall back to simpler intrinsics.

Disable any fallthrough on HLSL. Risky business if fallthrough blocks
had a barrier(), but can't do anything about that ...

45805857e5 MSL: De-virtualize get_declared_struct_member_size. 
It does not make sense to use a virtual call in the Compiler base class
here. Make it clearer by renaming the MSL-specific version to _msl.

c365cc1b43 Deal with OpPhi and case fallthrough. 
This is quite complex since we cannot flush Phi inside the case labels,
we have to do it outside by emitting a lot of manual branches ourselves.

This should be extremely rare, but we need to handle this case.

e2c95bdcbc MSL: Rewrite how resource indices are fallback-assigned. 
We used to use the Binding decoration for this, but this method is
hopelessly broken. If no explicit MSL resource remapping exists, we
remap automatically in a manner which should always "just work".

d81bfc5b58 MSL: Fix regression with Private parameter declaration. 
If we compile multiple times due to forced_recompile, we had
deferred_declaration = true while emitting function prototypes which
broke an assumption. Fix this by clearing out stale state before leaving
a function.
