PR tree-optimization/84362
* tree-ssa-loop-im.c: Include alias.h, builtins.h and tree-dfa.h.
(struct im_mem_ref): add ref_canonical flag.
(struct mem_ref_hasher): Use ao_ref as compare_type.
(mem_ref_hasher::equal): Adjust and add variant comparing ao_ref
parts.
(mem_ref_alloc): Take ao_ref parameter, initialize ref_canonical
member.
(gather_mem_refs_stmt): Set up ao_ref early and do the lookup
using it. If we have non-equal refs canonicalize the one
in the hashtable used for insertion.
(tree_ssa_lim_initialize): Adjust.
* g++.dg/vect/pr84362.cc: New testcase.
