Hal Finkel 10ae865847 [PowerPC] Improve int_to_fp(fp_to_int(x)) combining
The old target DAG combine that allowed for performing int_to_fp(fp_to_int(x))
without a load/store pair is updated here with support for unsigned integers,
and to support single-precision values without a third rounding step, on newer
cores with the appropriate instructions.
