tree-optimization/97307 - improve sinking of loads
This improves the heuristics finding a sink location for loads that does
not cross any store.

PR tree-optimization/97307
* tree-ssa-sink.c (statement_sink_location): Change heuristic
for not skipping stores to look for virtual definitions
rather than uses.
* gcc.dg/tree-ssa/ssa-sink-17.c: New testcase.
* gcc.dg/vect/pr65947-3.c: XFAIL.
