2219c4a392 MSL: Support SPV_EXT_demote_to_helper_invocation for MSL 2.3. 
MSL 2.3 has everything needed to support this extension on all
platforms. The existing `discard_fragment()` function was given demote
semantics, similar to Direct3D, and the `simd_is_helper_thread()`
function was finally added to iOS.

I've left the old test alone. Should I remove it in favor of these?

66afe8c499 Implement a simple evaluator of specialization constants. 
In some cases, we need to get a literal value from a spec constant op.
Mostly relevant when emitting buffers, so implement a 32-bit integer
scalar subset of the evaluator. Can be extended as needed to support
evaluating any specialization constant operation.

4cf840ee7b MSL: Support layered input attachments. 
These need to use arrayed texture types, or Metal will complain when
binding the resource. The target layer is addressed relative to the
Layer output by the vertex pipeline, or to the ViewIndex if in a
multiview pipeline. Unlike with the s/t coordinates, Vulkan does not
forbid non-zero layer coordinates here, though this cannot be expressed
in Vulkan GLSL.

Supporting 3D textures will require additional work. Part of the problem
is that Metal does not allow texture views to subset a 3D texture, so we
need some way to pass the base depth to the shader.

cab7335e64 MSL: Don't set the layer for multiview if the device doesn't support it. 
Some older iOS devices don't support layered rendering. In that case,
don't set `[[render_target_array_index]]`, because the compiler will
reject the shader in that case. The client will then have to unroll the
render pass manually.

53080ecca8 MSL: Fix multiview view index calculation with a non-zero base instance. 
Account for a non-zero base instance when calculating the view index and
the "real" instance index. Before, it was likely broken with a non-zero
base instance, since the calculated instance index could be less than
the base instance.

a07441568e Overhaul how we deal with reserved identifiers. 
- Do not silently drop reserved identifiers in the parser. This makes it
  possible to reflect identifiers which are reserved by the
  cross-compiler module.
- Instead of dropping the name, emit _RESERVED_IDENTIFIER_FIXUP in the
  source to make it clear that a name has been rewritten.
- Document what is reserved and not.

3347b1076d MSL: Fix handling of matrices and structs in the output control point array. 
Prior to this point, we were treating them as flattened, as they are in
old-style tessellation control shaders, and still are for structs in
new-style shaders. This is not true for outputs; output composites are
not flattened at all. This semantic mismatch broke a Vulkan CTS test.
It should now pass.
