Avoid sharing RTL if they need to be changed. * config/i386/i386.c (ix86_expand_movstr): Rework rep_mov and strmov handling so that memory attributes are preserved. Don't call ix86_set_move_mem_attrs. (ix86_set_move_mem_attrs_1, ix86_set_move_mem_attrs): Removed. (ix86_expand_clrstr): Rename src argument to dst. Rework rep_stos and strset handling so that memory attributes are preserved. (ix86_expand_strlen): Pass src argument to ix86_expand_strlensi_unroll_1. Rework strlenqi_1 handling so that memory attributes are preserved. (ix86_expand_strlensi_unroll_1): Add src argument. Use change_address instead of gen_rtx_MEM. * config/i386/i386.md (strmov, strmov_singleop, rep_mov): New expanders. (strmovdi_rex64, strmovsi, strmovsi_rex64, strmovhi, strmovhi_rex64, strmovqi, strmovqi_rex64): Remove. (rep_mov*, strmov*): Prefix insn names with *.

(cmpstrqi_nz_1, cmpstrqi_1): New expanders. (strlenqi_1, strlenqi_rex_1): Prefix insn names with *.
