This CL removes the `fallthrough` parsing from the WGSL parser. The
`fallthrough` token is left so we can generate a nicer error message
in the case `fallthrough` is used.

This is the same as was done for const eval builtin tests, allowing the
error cases to be defined in the same place as we define the positive
cases.
Also got rid fo the 'overflow' flag, which was used to skip abstract
cases in the unit test. Instead, I modified the tests to only add
overflow cases if not abstract.
This change will make it easier to update tests when we make Inf/NaN
failures for concrete float operations.

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).
