Ryan Houdek 8bfae631b1 Frontend: Support raising unimplemented instruction on LOCK failure
When the LOCK prefix is on an instruction that doesn't support LOCK then
it raises a SIGILL. Make sure to pass that up.

Additionally if the instruction does support lock prefix, has a lock
prefix, but the destination is not memory then that is also invalid.
