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.
