Message:

Implement the B3 equivalent of FTLCompile
​https://bugs.webkit.org/show_bug.cgi?id=151370

Reviewed by Benjamin Poulain.

This adds a B3 version of FTLCompile and gets the data structures related to installing an FTL
compilation (i.e. the finalizer and JITCode) to be aware of B3. That requires stubbing a lot of stuff
out and also simplifying a lot of code around having everything inside a single contiguous chunk of
JIT code rather than some opaque JIT code handles plus miscellaneous side-codes. This compiles but
crashes because lowering isn't done yet.
