target-ppc: Rename helper_compute_fprf to helper_compute_fprf_float64
Since helper_compute_fprf() works on float64 argument, rename it
to helper_compute_fprf_float64(). Also use a macro to generate
helper_compute_fprf_float64() so that float128 version of the same
helper can be introduced easily later.
