Fixes#2488
* Validator doesn't identify back-edge of the loop, so the merge is
never set
* Construct::blocks() has safe uses of `merge` so the assert can be
removed
* Added a test
Changing the stored value for a sampled image consumer to be the
instruction instead of result ID, since not all instructions have
result IDs. Using result IDs led to a potential crash when using
OpReturnValue, which doesn't have a result ID. OpReturnValue is not a
legal consumer, but the validator needs to look at the instruction to
determine this, thus storing the pointer to the instruction, instead
of trying to fetch the pointer using the instruction.
Issue #1528 covers fixing the check.
Fixes#2463
If relax-logical-pointer is enabled, this commit makes Validator
accept function param even when its Storage Class is different from
the expected one.

In WebGPU all blocks are required to be reachable, unless they are one of two
specific degenerate cases for merge-block or continue-target. This PR adds in
checking for these conditions.
Fixes#2068
In relaxed addressing mode, we want to accept non memory objects
because this is a very natural translation of hlsl. It should be fixed
by legalization by inlining the calls.
This is required to properly handle uses of forward declared ids. Since forward
declared ids were not being properly covered by the validator this uncovered a
bunch of small issues that needed to be resolved to get tests passing again.
Fixes#2373
* Remove the static maps from CheckDecorationsCompatibility
There are a few data structures in the function
`CheckDecorationsCompatibility` that are allocated using `new` and their
address is stored in a static pointer. This code pattern causes the
MSVC memory leak checker to say there is a memory leak. Some people
are interested in keeping that clean.
To work around it, I have replaced them with either a function or an
array of POD types. The array can be kept as a static directly because
it has a trivial destructor, and we don't have to worry about it being
destroyed too early.

This CL adds in the specific checks required for WebGPU, enables
running the builtin checks for WebGPU, and refactors the existing
testing infrastructure to support testing the new checks.
This PR is part of resolving #2276
In a recent PR, we allowed a forward reference for the element type in
an array declaration. However, we do not have other check to make sure
the forward reference is a pointer type first reference in
OpTypeForawrdPointer. We add that check.
