    cfgrtl: Fix up -g vs. -g0 code generation -flto differences in
fixup_reorder_chain [PR104589]

    This is similar to PR104237 and similarly to that, no testcase included
    for the testsuite, as we don't have a framework to compile/link with
    -g -flto and -g0 -flto and compare -fdump-final-insns= results from
    the lto1 compilations.

    With -flto, whether two location_t compare equal or not and just
    express the same location is a lottery.

            * cfgrtl.c (fixup_reorder_chain): Use loc_equal instead of direct
            INSN_LOCATION comparison with goto_locus.
