FXC fails to compile when it determines that the rhs of an integral
division is zero with "error X4010: Unsigned integer divide by zero".
bclayton's fix (https://dawn-review.googlesource.com/c/tint/+/60500)
addressed cases for division by an integer constant 0. This CL adds the
missing support for division by integral vectors with 0 components.
FXC also fails on division by integral expressions that it can fold to
0. To handle these cases, we now emit a runtime check for 0 and replace
by 1. In the cases I've tested, FXC seems able to optimize these checks
away.

There are a few places where a branch or return is created,
conditionally on whether a terminator was the last thing seen.
The goal is to generate a SPIR-V basic block terminator exactly
when needed, and to avoid generating a branch or return immediately
after a prior terminator.
Previously, the decision was based on the last thing seen in the AST.
But we should instead check the emitted SPIR-V instead.
This fixes cases such as a break or return inside an else-if.
That's because an if/elseif is actually a selection inside a selection.
Looking at the AST only works when trying to terminate the *inside*
selection. In the outer recursive call, the last AST node is
no longer a terminator, and we would skip generating the branch
to the merge block.

Vulkan allows them, but WGSL does not.
A duplicate decoration is purely redundant.
A parameterized decoratio with different parameterization is

So for each target, only take the first decoration of each kind.

FXC fails to compile code that assigns to dynamically-indexed fixed-size
arrays in structs on internal shader variables with:
error X3500: array reference cannot be used as an l-value; not natively
addressable
This CL detects this case, and transforms such assignments into copying
out the array to a local variable, assigning to that local, and then
copying the array back.
Also manually regenerate SKIPs for HLSL/FXC after this change, which
fixes 30 tests. Also exposes some "compilation aborted unexpectedly" now
that "array reference cannot be used as an l-value" has been fixed. For
tests that fail for both DXC and FXC, updating SKIPs to the DXC one to
help distinguish actual FXC bugs from valid errors.
