* rtl.h (locator_eq): New decl.
* cfglayout.c (locator_scope): New function.
(insn_scope): Use it.
(locator_eq): New function.
(fixup_reorder_chain): Search for last insn in src bb
that has locator set or first insn in dest bb. Use
locator_eq instead of == to compare locators.
* cfgrtl.c (cfg_layout_merge_blocks): Likewise.
* cfgcleanup.c (try_forward_edges): Use locator_eq instead of
== to compare locators.
