powerpc: wordcopy/memmove cleanup for ppc32

This patch cleanup some multiarch code related to memmmove
optimization. Initial IFUNC support added specialized wordcopy
symbols which turned in local IFUNC calls used by memmove default
implementation.  The patch removes the internal IFUNC for wordcopy
symbols and uses local branches in the memmmove optimization instead.
