Compiler cleanup: remove some old JIT leftovers.

The JIT was designed to allow any code emitter (for any reason)
to decline to complete a codegen request.  The outer driver
would then detect if a codegen request wasn't completed and
in that case generate bail-out code to the interpreter or
simply end the trace early.

This was quite useful for the JIT, but has no value in an
ahead-of-time compiler (with the exception of special inline
cases - those are still optional).  Codegen requests must succeed or
die.  This CL removes some of the bool success reporting from
inherited Gen routines.
