This patch intends to unify both strcpy and stpcpy implementationsi for PPC64 and PPC64/POWER7. The idead default powerpc64 implementation is to provide both doubleword and word aligned memory access. For PPC64/POWER7 is also provide doubleword and word memory access, remove the branch hints, use the cmpb instruction for compare doubleword/words, and add an optimization for inputs of same alignment.
