[PowerPC] Make use of VSX f64 <-> i64 conversion instructions

When VSX is available, these instructions should be used in preference to the
older variants that only have access to the scalar floating-point registers.

Add more PPC floating-point conversion instructions

The P7 and A2 have additional floating-point conversion instructions which
allow a direct two-instruction sequence (plus load/store) to convert from all
combinations (signed/unsigned i32/i64) <--> (float/double) (on previous cores,
only some combinations were directly available).
