Leandro Lupori e16c18650c [PPC64] memcpy/memmove/bcopy optimization
For copies shorter than 512 bytes, the data is copied using plain
ld/std instructions.
For 512 bytes or more, the copy is done in 3 phases:

Phase 1: copy from the src buffer until it's aligned at a 16-byte boundary
Phase 2: copy as many aligned 64-byte blocks from the src buffer as possible
Phase 3: copy the remaining data, if any

In phase 2, this code uses VSX instructions when available. Otherwise,
it uses ldx/stdx.
