re PR debug/52001 (Huge compile-time regression with var-tracking)
PR debug/52001
* alias.c (refs_newer_value_cb, refs_newer_value_p): New.
(get_addr): Walk canonical value's locs. Avoid returning VALUEs
and locs that reference values newer than the non-canonical value
at hand. Return the canonical value as a worst case.
(memrefs_conflict_p): Walk canonical value's locs.
