* 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.
(promote_duplicated_reg_to_size): Do not look into desired alignments when
doing vector expansion.
(ix86_expand_setmem): Track better when promoted value is available; choose unroll factors
more sanely.; output loopy epilogue only when needed.
