10965 cost of sqrt 20->14, DIVSS 18->13, DIVSD 32->17, SQRtSS 30->14
10966 and SQRTsD 58->18, cond_not_taken_branch_cost. 2->1. Increase

10981 * expr.c (expand_assignment): Fix up a typo in simplify_gen_subreg
10982 last argument when extracting from CONCAT. If either from_real or
10983 from_imag is NULL, use expansion through memory. If result is not
10984 a CONCAT and simplify_gen_subreg fails, try to simplify_gen_subreg
10985 the parts directly to inner mode, if even that fails, use expansion
10986 through memory.

10989 * expmed.c (expand_shift_1): For 2-byte rotates by BITS_PER_UNIT,
10990 check for bswap in mode rather than HImode and use that in expand_unop
10991 too.
