tree-optimization/100923 - re-do VN with contextual PTA info fix
The following implements the gist of the PR100923 fix in a leaner
(and more complete) way by realizing that all ao_ref_init_from_vn_reference
uses need to have an SSA name in the base valueized with availability
in mind. Instead of re-valueizing the whole chain of operands we can
simply only and always valueize the SSA name we put in the base.
This handles also two omitted places in vn_reference_lookup_3.
PR tree-optimization/100923
* tree-ssa-sccvn.cc (ao_ref_init_from_vn_reference): Valueize
base SSA_NAME.
(vn_reference_lookup_3): Adjust vn_context_bb around calls
to ao_ref_init_from_vn_reference.
(vn_reference_lookup_pieces): Revert original PR100923 fix.
(vn_reference_lookup): Likewise.
