Added files:

Log message:
PR rtl-optimization/17581
* cselib.c (cselib_process_insn): The last instruction of a libcall
block, with the REG_RETVAL note, should be considered in the libcall.
* gcse.c (do_local_cprop): Allow constants to be propagated outside
of libcall blocks.
(adjust_libcall_notes): Use simplify_replace_rtx instead of
replace_rtx to avoid creating invalid RTL in REG_RETVAL notes.
* gcc.dg/pr17581-1.c: New test case.
