Subject: [RS6000 PATCH] Remove contraints from define_expand's.

As requested the following patch removes the register allocation
constraints from the match_operand clauses of my recently added popcount
and parity define_expands.  Whilst I was there I also cleaned up the other
instances of this issue in rs6000.md.

The following patch has been bootstrapped on powerpc-ibm-aix5.2.0.0 with a
full "make bootstrap", all default languages, and regression tested with a
top-level "make -k check" with no new failures.

Ok for mainline?

        * config/rs6000/rs6000.md (ctz<mode>2, ffs<mode>2, popcount<mode>2,
        parity<mode>2, smulsi3_highpart, abstf2_internal, allocate_stack,
        tablejumpdi, movsi_to_cr_one): Remove constraints from
        define_expand's match_operands.
