Trap to the debugger properly after BackPatch failure.
Remove profiled re-JIT support in JitIL.

It's extremely unsafe, unused (not exposed in the GUI and not present in
any gameconfigs), and mostly obviated by fastmem.  Although this type of
thing could theoretically be useful someday for fastmem support with
MMU, it's probably not the best way to do it, the existing
implementation is way too simplistic, and it can always be dug up to
provide support for a new implementation if needed.

Not like it's a big deal to keep it working, but it really seems
pointless.
Finish replacing ThunkManager with ABI_PushRegistersAndAdjustStack.

As part of that, change SafeLoadToEAX to SafeLoadToReg, and have JitIL
use that, which should fix fastmem on JitIL.

This should also fix a potential stack corruption issue with x86.
Fix stfd, which was broken in the fastmem writes commit.
