* doc/tm.texi (SET_RATIO, SET_BY_PIECES_P): Document new macros.
(STORE_BY_PIECES_P): No longer applies to __builtin_memset.
* expr.c (SET_BY_PIECES_P): Define.
(can_store_by_pieces, store_by_pieces): Add MEMSETP argument; use
it to decide whether to use SET_BY_PIECES_P or STORE_BY_PIECES_P.
(store_expr): Pass MEMSETP argument to can_store_by_pieces and
store_by_pieces.
* expr.h (SET_RATIO): Define.
(can_store_by_pieces, store_by_pieces): Update prototypes.
* builtins.c (expand_builtin_memcpy): Pass MEMSETP argument to
can_store_by_pieces/store_by_pieces.
(expand_builtin_memcpy_args): Likewise.
(expand_builtin_strncpy): Likewise.
(expand_builtin_memset_args): Likewise. Also remove special case
for optimize_size so that can_store_by_pieces/SET_BY_PIECES_P can
decide what to do instead.
* value-prof.c (tree_stringops_transform): Pass MEMSETP argument
to can_store_by_pieces.
* config/sh/sh.h (SET_BY_PIECES_P): Clone from STORE_BY_PIECES_P.
* config/s390/s390.h (SET_BY_PIECES_P): Likewise.
* config/mips/mips.opt (mmemcpy): Change from Var to Mask.
* config/mips/mips.c (override_options): Make -Os default to -mmemcpy.
* config/mips/mips.h (MIPS_CALL_RATIO): Define.
(MOVE_RATIO, CLEAR_RATIO, SET_RATIO): Define.
(STORE_BY_PIECES_P): Define.
