PR bootstrap/51134 * i386.c (atom_cost): Fix 32bit memset description. (expand_set_or_movmem_via_loop_with_iter): Output proper bounds check for epilogue loops. (expand_movmem_epilogue): Handle epilogues up to size 15 w/o producing byte loop. (decide_alg): sse_loop is not useable wthen SSE2 is disabled; when not optimizing always use rep movsb or lincall; do not produce word sized loops when optimizing memset for size (to avoid need for large constants). (ix86_expand_movmem): Get into sync with ix86_expand_setmem; choose unroll factors better; always do 128bit moves when producing SSE loops; do not produce loopy epilogue when size is too small.
