Add PPC FP rounding instructions fri[mnpz]

These instructions are available on the P5x (and later) and on the A2. They
implement the standard floating-point rounding operations (floor, trunc, etc.).
One caveat: frin (round to nearest) does not implement "ties to even", and so
is only enabled in fast-math mode.

PowerPC: Lowering floor intrinsic for Altivec

This patch lowers the llvm.floor, llvm.ceil, llvm.trunc, and
llvm.nearbyint to Altivec instruction when using 4 single-precision
float vectors.
