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.
