[LICM] Report failing to hoist a load with an invariant address These are interesting because lack of precision in alias information could be standing in the way of this optimization. An example is the case in the test suite that I showed in the DevMeeting talk: http://lab.llvm.org:8080/artifacts/opt-view_test-suite/build/MultiSource/Benchmarks/FreeBench/distray/CMakeFiles/distray.dir/html/_org_test-suite_MultiSource_Benchmarks_FreeBench_distray_distray.c.html#L236 canSinkOrHoistInst is also used from LoopSink, which does not use opt-remarks so we need to take ORE as an optional argument.
