Most of this change is fixing up the numerious tests that violated this rule.

It seems we haven't run our e2e tests with FXC validation in a long time
- at least not since we've added the vk-gl-cts corpus.
Locally disabled exclusion of "/test/vk-gl-cts/" in test-runner/main.go,
and ran:
./test/test-all.sh out/build/x64-Debug/tint.exe --format hlsl --fxc --generate-skip
These will need to be manually removed once the skips aren't needed by
deleting them all, and re-running as above.

Migrate some of the validation logic over to use the results of behavior
analysis.
The most significant changes are:
* Unreachable-statements now consider merge-points of control flow. For
example, if all branches of a if-statement or switch-statement either
return or discard, the next statement will be considered unreachable.
* Unreachable statements are no longer an error, but a warning. See
https://github.com/gpuweb/gpuweb/issues/2378.
* Statements that follow a loops that does not break, or have a
conditional will now be considered unreachable.
* Unreachable statements produced by the SPIR-V reader are now removed
using the new RemoveUnreachableStatements transform.
Some other new changes include additional validation for the continuing
block for for-loops, to match the rules of a loop continuing block.
The new cases this validation is testing for are not expressible in
WGSL, but some transforms may produce complex continuing statements that
might violate these rules. All the writers are able to decay these
complex for-loop continuing statements to regular loops.

Some pass DXC, but not FXC (e.g. continue_in_switch).
Some now pass (e.g intrinsics/gen/atan2/*.hlsl)
Some now fail gracefully instead of asserting (e.g. 807.spv)

The `Ignore()` intrinsic is about to be deprecated, so don't use it for testing.

Metal 1.x does not support swizzling on packed_vec types.
Use array-index for single element selection (permitted on LHS and RHS of assignment)
Cast the packed_vec to a vec for multiple element swizzles (not permitted as the LHS of an assignment).

The new vk-gl-cts tests have uncovered a whole bunch of FXC issues,
which have been filed as tint bugs.
