tree-optimization/110669 - bogus matching of loop bitop
The matching code lacked a check that we end up with a PHI node
in the loop header. This caused us to match a random PHI argument
now catched by the extra PHI_ARG_DEF_FROM_EDGE checking.
PR tree-optimization/110669
* tree-scalar-evolution.cc (analyze_and_compute_bitop_with_inv_effect):
Check we matched a header PHI.
* gcc.dg/torture/pr110669.c: New testcase.
