GCC 4.8 enables -ftree-loop-distribute-patterns at -O3 by default and this optimization may transform loops into memset/memmove calls. Without proper handling this may generate unexpected PLT calls on GLIBC. This patch fixes by create memset/memmove alias to internal GLIBC __GI_memset/__GI_memmove symbols.
