  [PowerPC] Improve codegen for vector fp to int widening conversions

We currently do not utilize instructions that convert single
precision vectors to doubleword integer vectors. These conversions
come up in code occasionally and this improvement allows us to
open code some functions that need to be added to altivec.h.
