Passing a dereferenced value from Hashmap::Find() directly into Hashmap::Add() is a potential cause of UAF, as the insertion may reallocate the map, invalidating the input reference.
I'll try to think of ways to make this foot-gun harder to do, but this CL fixes the immediate bug found by fuzzers.

Discard statements no longer affect the behavior or uniformity
analysis. Update the resolver, validator, and several tests to reflect
this.
Some E2E tests were removed as they had loops that are now considered
to be infinite.
Use the DemoteToHelper transform to emulate the correct semantics on
platforms where discard is (or may) terminate the invocation in a
manner that would affect derivative operations.
We no longer need the UnwindDiscardFunctions transform for HLSL, which
already implements the correct semantics. However, we still run the
DemoteToHelper transform for the HLSL backend due to issues with FXC's
handling of discard statements (see crbug.com/tint/1118).

In WGSL, we can shift left abstracts by >= 64, as long as the result is
representable in the data type we choose for it. When shifting 0, we can
shift by any positive u32 value (result is always 0), but in C++, it's
UB to shift by more than the bit width of the data type, so we need to
handle this. This bug was caught by ClusterFuzz.

now it has testcases for both function, private, and storage address
space array variable, with and without explicit initializer, and array

This allows the value to be declared in a `const` expression, and to use arithmetic.

Similar to the handling of packed values in the arithmetic operators
the shift operators need to cast to the unpacked type before doing the
as_type casts.

In 104681 the vectors were cast to themselves to fixup an issue
with `packed_int`. That CL used an `as_type` which does a bit cast.
A `packed_int` can not be bitcast to an `int`. This CL changes to
a type cast, so instead of `as_type<int3>()` it does `int3()`.

This CL adds element count limits to arrays. In FXC there is a maximum
of 65536 elements in an array. This limit is not yet in WGSL, but adding
this here allows us to fix the issue with large arrays and GLSL.

Currently in the MSL backend we cast int values to uint in order to get
the correct WGSL behaviour for over/under flow. This fails in the case
of host shareable buffers as they use `packed` types which need to get
cast to the non-packed version first.

I added the forcing of the "loop" attribute to all loops to address FXC
failing on uniformity errors related to gradients in loops. Since then,
Tint now implements UA and it recently became an error, so we no longer
need this hack. As a result, FXC is now better able to cope with loops
that it determines executes 0 times.
Most e2e tests are affected because so many use loops, but 27 tests that
were previously failing are now passing with this change:
