3da5bc7a57 GLSL: Forward declare non-block BDA types as well. 
With non-block structs, we can have pointers in those types too.

871ac0e5b7 GLSL: Handle BDA to plain non-block struct. 
The implementation assumed that BDA to struct would always result in a
Block-like type, but that is not necessarily the case. Treat non-Block
structs as POD types as well.

be944258be GLSL: Ignore bogus constant/undefs which use block types. 
This is banned in more recent SPIR-V.
We cannot implement this in any reasonable way since block types don't
participate as normal types in GLSL.

79d63934a6 GLSL: Emit inline invariant position for mesh shaders. 
Work around missing feature from GLSL. Normally we can emit a global
invariant gl_Position; and call it a day, but it does not work for mesh
shaders it seems. Declaring invariance inside an explicit IO block works
fine on the other hand ...

cfd1618e31 MSL: Use templated array type when emitting BDA to arrays. 
Handling native array types is not really feasible since we need to fuse
the variable declaration with the type declaration.

This is feasible in something like variable_decl, but for plain SSA
pointers, this breaks down.

68a012a4f2 CFG: Handle implied access to opaque loaded values. 
Similar concern as access chains. Objects that we cannot lower to
temporaries must implicitly access all expression dependencies when they
are themselves accessed.

5547b25afe Interleave undef values with constants and types. 
Undef values may be of struct type and may be used in constants.
Therefore, they must be interleaved with constants and types.

Fixes the rest of the Vulkan CTS test
`dEQP-VK.spirv_assembly.instruction.compute.opundef.undefined_spec_constant_composite`.

(Please excuse the churn in the reference output; it's an inevitable
result of this change.)

05bbcc2d09 Do not optimize OpCompositeInsert for hoisted temporaries. 
We cannot track uses that happens in subsequent loop iterations, so have
to be very careful.

be904dcc1e Handle collapsed loops similar to collapsed selections. 
If we hit the deprecated scenario of selection with identical branches,

f7e98c39db Avoid detection of false loop variables. 
If the loop variable candidate has a dominating block that lives in an
unrelated loop, we have to reject the loop variable candidate.

23662668dd Attempt more optimal codegen for OpCompositeInsert. 
Speculate that we can modify the SSA value in-place. As long as it is
not used after the modify, this is fine.

Also need to make sure we don't attempt to RMW something that is
impossible to modify.

7a6c2da9aa GLSL: Handle more proper semantics for RelaxedPrecision. 
GLSL and RelaxedPrecision are quite different in what they affect.
RelaxedPrecision affects operations, while this is merely implied in
GLSL based on inputs.

This leads to situations where we have to promote mediump inputs to
highp, and the simplest approach is to force highp temporaries for
inputs which are consumed in a highp context. For completeness, we also
demote RelaxedPrecision inputs to mediump variables.

PHI is handled by copying the PHI into a temporary.

We have to be very careful with hoisted temporaries, since the child
temporary will not be analyzed up-front. We inherit the hoisted-ness
state and emit the hoisted child temporary as necessary. When faking the
temporaries with OpCopyObject, we make sure to block any variable
hoisting.

Hoisting children of PHI variables is fine, since PHIs are not hoisted with
the same framework as other temporaries.
