tree-optimization/111444 - avoid insertions when skipping defs
The following avoids inserting expressions for IPA CP discovered
equivalences into the VN hashtables when we are optimistically
skipping may-defs in the attempt to prove it's redundant.
PR tree-optimization/111444
* tree-ssa-sccvn.cc (vn_reference_lookup_3): Do not use
vn_reference_lookup_2 when optimistically skipping may-defs.
* gcc.dg/torture/pr111444.c: New testcase.
