Summary: The goal is to start moving us closer to the model where RuntimePointerChecking will compute and store the checks. Then a client can filter the check according to its requirements and then use the filtered list of checks with addRuntimeCheck. Before the patch, this is all done in addRuntimeCheck. So the patch starts to split up addRuntimeCheck while providing the old API under what's more or less a wrapper now. The new underlying addRuntimeCheck takes a collection of checks now, expands the code for the bounds then generates the code for the checks. I am not completely happy with making expandBounds static because now it needs so many explicit arguments but I don't want to make the type PointerBounds part of LAI. This should get fixed when addRuntimeCheck is moved to LoopVersioning where it really belongs, IMO. Audited the assembly diff of the testsuite (including externals). There is a tiny bit of assembly churn that is due to the different order the code for the bounds is expanded now (MultiSource/Benchmarks/Prolangs-C/bison/conflicts.s and with LoopDist on 456.hmmer/fast_algorithms.s).
