Adam Nemet 15840393f3 [LAA] Make the set of runtime checks part of the state of LAA, NFC 
This is the full set of checks that clients can further filter. IOW,
it's client-agnostic.  This makes LAA complete in the sense that it now
provides the two main results of its analysis precomputed:

1. memory dependences via getDepChecker().getInsterestingDependences()
2. run-time checks via getRuntimePointerCheck().getChecks()

However, as a consequence we now compute this information pro-actively.
Thus if the client decides to skip the loop based on the dependences
we've computed the checks unnecessarily.  In order to see whether this
was a significant overhead I checked compile time on SPEC2k6 LTO bitcode
files.  The change was in the noise.

The checks are generated in canCheckPtrAtRT, at the same place where we
used to call groupChecks to merge checks.
