* expmed.c (expand_sdiv_pow2): New function to expand signed division
by a positive power of two, split out from expand_divmod.  Provide
an alternate implementation when shifts are expensive.  Lower the
threshold for using a branchless implementation to BRANCH_COST >= 2.
(expand_divmod): Call expand_sdiv_pow2 for suitable divisions.
