* dse.c (struct insn_info): Mention frame_read set also
before reload for tail calls on some targets.
(scan_insn): Revert 2014-12-22 change. Set frame_read
also before reload for tail calls if
HARD_FRAME_POINTER_IS_ARG_POINTER. Call add_wild_read
instead of add_non_frame_wild_read for non-const/memset
tail calls after reload.
