re PR rtl-optimization/42294 (ICE in code_motion_path_driver for 416.gamess)

        PR rtl-optimization/42294
        * sel-sched.c (try_replace_dest_reg): When chosen register
        and original register is the same, do not bail out early, but
        still check all original insns for validity of replacing destination
        register.  Set EXPR_TARGET_AVAILABLE to 1 before leaving function
        in this case.
