Shuffle the transform orders to ensure that these are embedded in a structure before running the Std140 transform.

We already compute the "first" and "last" basic block that
uses a value, so we could know when to hoist a value into
a var declaration. You have to do this sometimes to make
sure all uses are in scope of the declaration.
Until now we tracked Phis with an entirely different mechanism.
But there are cases which broke down. That's what happens
in crbug.com/tint/1649.
Additionally, GraphicsFuzz cases generarte similar weirdness.
Also, be more careful about ensuring that the assignments
generated to feed phis behave as if they occur in parallel.
Within a single batch of such assignments, generate and
use intermediate let-declarations for phis that that batch
will overwrite.
Also, unwrap-references when rectifying the signedness of
binary operators.

Since GLSL ES does not support the offset= attribute, struct members
with explicit @align or @size attributes require adding explicit
padding members. This in turn requires rewriting any constructor
calls to initialize the new padding to zero, handled in the same
transform.
Note that this is currently overly-verbose, and will add padding where
GLSL doesn't technically need it (e.g., padding a vec3 out to 16 bytes).

If the let initializer was an abstract numeric that was implicitly materialized to a concrete type, then we could inlining the initializer into the use without the implicit materialization cast.
This could lead to validation errors, and subtly different results in the program.
In this situation, add an explicit cast to keep the types the same before and after inlining.

occur for a binary operation, say AFloat + AInt. Before constant

This extension adds support for the push_constant storage class such
that it can be tested with WGSL test files. The real goal is to allow
future transforms that will add push constants that the SPIRV writer
will output.
The extension:
- Adds the `chromium_experimental_push_constant` enable.
- Allows the push_constant storage class for global variables.
- Adds validation that the types are host-shareable for push_constant
variables, and that they don't contain f16 (must be 32bit types
only).
- Validates that at most one push_constant variable is statically used
per entry-point.
- Skips validation that the extension has been enabled if
kIgnoreStorageClass is used.
Tests are added:
- For parsing of var<push_constant>
- Caught a missing conversion.
- For each of the validation rules.
- For the wrapping of push constants in structs if needed by
AddSpirvBlockAttribute.
- For the layout and type rules of the storage class.
- For a shader with multiple entry-points using various push constants.
- Caught a missing reset of the previous push constant variable in
the validation check that at most one is used.
- Caught the missing wrapping in structs that had to be added to
AddSpirvBlockAttribute.
- Caught incorrect logic when adding diagnostics about the call
graph leading to the reference to push constants.

Invalid by SPIR-V 1.6 Rev2 update to validation rules:
- Block 80 is a structurally reachable continue target
- Block 25 is not structually reachable, and not part of the loop,
but branches to 80.
vk-gl-cts/graphicsfuzz/cov-dead-branch-func-return-arg/0-opt.*
- The continue construct with the continue target 37[%37]
is not structurally post dominated by the back-edge block 64[%64]
- The SPIRV-Tools inliner no longer creates such cases. It splits the
single-block loop and pushes the continue target down.
vk-gl-cts/graphicsfuzz/nested-for-loops-with-return/0-opt.spvasm
- The loop headed at block 46 does not structurally dominate its merge
block 44. There is a continue-target edge from 41 to 44.

- Continue target 20 also its own loop header, but is not structurally

- Delete the end-to-end test.
- Keep the unit test because it's about classifying edges, but disable dumping

Module-scope 'let' is getting replaced by 'const'. For all backends,
'const' will be inlined into the place of usage, making most of these

And remove the WrapArraysInStructs transform.
Wrapping arrays in structures becomes troublesome for `const` arrays, as
currently WGSL does not allow `const` structures.
MSL 2.0+ has a builtin array<> helper, but we're targetting MSL 1.2, so
we have to emit our own. Fortunately, it can be done with a few lines of
templated code.
This produces significantly cleaner output.
