BR 3392279: Fix duplicated REX prefixes
The fix for BR 3392278:
aa29b1d93f5a assemble.c: Don't drop rex prefix from instruction itself
... would cause multiple REX prefixes to be emitted for some
instructions. Create a new flag to indicate that REX has already been
emitted, which can be cleared for each instance of an instruction.
