This adds a fake toolchain for pointer compression, used for correctness fuzzing. The toolchain enables us to have an extra build with inverse pointer-compression defaults side-by-side. The extra build is used similarly to existing x64/x86 comparisons, except that we now compare builds with different compile-time flags.

We now handle these differently and we move to fast handlers even without going through premonomorphic state after this cl: https://chromium-review.googlesource.com/c/v8/v8/+/1807356. Also, with lazy feedback this would be a relatively uncommon case anyway. So, we no longer need premonomorphic state. This cl removes this state entirely.
