- Changed to use a pseudo instruction `PATCHABLE_OP`, as per @dberris, the code looks a lot cleaner now!
- Renamed `"prologue-hotpatch-compact"` to `"prologue-short-redirect"`

There is some cleanup we can do after this, that I'll do separately
once this lands:

- Simplify `StackMapShadowTracker`
- Split out `EmitNops` so that the assert using `OnlyOneNop` can instead live in its caller.
