tree-optimization/112939 - VN PHI visiting and -ftrivial-auto-var-init
The following builds upon the last fix, making sure we only value-number
to visited (un-)defs, otherwise prefer .VN_TOP.
PR tree-optimization/112939
* tree-ssa-sccvn.cc (visit_phi): When all args are undefined
make sure we end up with a value that was visited, otherwise
fall back to .VN_TOP.
* gcc.dg/pr112939.c: New testcase.
