intel/fs/cse: Split create_copy_instr into three cases

Previously, we tried to combine all cases where the instruction being
CSE'd writes to more than one MOV worth of registers into one case with
a bit of special casing for LOAD_PAYLOAD.  This commit splits things so
that LOAD_PAYLOAD is entirely it's own case.  This makes tweaking the
LOAD_PAYLOAD case simpler in the next commit.
