Sean Silva 284b0324e2 [PM] Avoid getResult on a higher level in LoopAccessAnalysis
Note that require<domtree> and require<loops> aren't needed because they
come in implicitly via the loop pass manager.

Adam Nemet d7037c56d3 [LAA] LLE 2/6: Fix a NoDep case that should be a Forward dependence
Summary:
When the dependence distance in zero then we have a loop-independent
dependence from the earlier to the later access.

No current client of LAA uses forward dependences so other than
potentially hitting the MaxDependences threshold earlier, this change
shouldn't affect anything right now.

This and the previous patch were tested together for compile-time
regression.  None found in LNT/SPEC.
