Remove profiled re-JIT support in JitIL.

Browse Source 
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.
