  [PowerPC][LoopVectorize] Extend getRegisterClassForType to consider double and other floating point type

In https://reviews.llvm.org/D67148, we use isFloatTy to test floating
point type, otherwise we return GPRRC.
So 'double' will be classified as GPRRC, which is not accurate.

This patch covers other floating point types.
