SSA renaming fix & invalid opcode fix
The old SSA renaming mechanism was able to take some shortcuts because
of the limited CFG shapes it encountered. Shortcut replaced and previous
workaround code removed.
Also fixes a regression introduced by the stack bounds checking change
which sometimes resulted in an (opcode < 0x200) assert failure, and
removes an optimization flag and associated code that no longer applicable.
