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.cc (fixup_reorder_chain): Use loc_equal instead of direct
INSN_LOCATION comparison with goto_locus.
