[PATCH 5/6] rs6000: New testsuite selectors

[Segher Boessenkool]

This introduces four new selectors for use with Power testcases:
longdouble64, ppc_float128, ppc_float128_insns, powerpc_vsx.

        * lib/target-supports.exp (check_effective_target_longdouble64,
        check_effective_target_ppc_float128,
        check_effective_target_ppc_float128_insns,
        check_effective_target_powerpc_vsx): New.
