There's a reason the overload of `ctx.Replace()` that takes a pointer to the replacement is deprecated - it doesn't play well when used as part of another replacement.
Switch to using the callback overload of Replace() to fix bad transform output.

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).

Replace the ShouldRun() method with Apply() which will do the

This reduces a bunch of duplicated scanning between the old ShouldRun()
and Transform().
This change also adjusts code style to make the transforms more
consistent.
