sw-1.c: Force rep;movsb.
* gcc.target/i386/sw-1.c: Force rep;movsb.
* config/i386/i386.h (processor_costs): Add second dimension to
stringop_algs array.
* config/i386/i386.c (cost models): Initialize second dimension of
stringop_algs arrays.
(core_cost): New costs based on generic64 costs with updated stringop
values.
(promote_duplicated_reg): Add support for vector modes, add
declaration.
(promote_duplicated_reg_to_size): Likewise.
(processor_target): Set core costs for core variants.
(expand_set_or_movmem_via_loop_with_iter): New function.
(expand_set_or_movmem_via_loop): Enable reuse of the same iters in
different loops, produced by this function.
(emit_strset): New function.
(expand_movmem_epilogue): Add epilogue generation for bigger sizes,
use SSE-moves where possible.
(expand_setmem_epilogue): Likewise.
(expand_movmem_prologue): Likewise for prologue.
(expand_setmem_prologue): Likewise.
(expand_constant_movmem_prologue): Likewise.
(expand_constant_setmem_prologue): Likewise.
(decide_alg): Add new argument align_unknown. Fix algorithm of
strategy selection if TARGET_INLINE_ALL_STRINGOPS is set; Skip sse_loop
(decide_alignment): Update desired alignment according to chosen move
mode.
(ix86_expand_movmem): Change unrolled_loop strategy to use SSE-moves.
(ix86_expand_setmem): Likewise.
(ix86_slow_unaligned_access): Implementation of new hook
slow_unaligned_access.
