Currently checks alignment and killing stores on a power of 2 boundary as this is likely
to trim the size of the earlier store without breaking large vector stores into scalar ones.

The SCEVAffFunc is now only used to express memory accesses. Give it a proper
name and rework the class such that this is obvious.

This also removes the construction of MayAliasSets that became invalid when
removing the use of SCEVAffFunc.

We do not use it anymore. It was replaced by SCEVVisitors like the
SCEVValidator.

This check was necessary because of the use AffineSCEVIterator in TempScopInfo.
As we removed this use recently it is not necessary any more.

lookups for Objective-C methods by selector.
Right now all it does is print log information.

Also improved the logging for imported TagDecls
to indicate whether or not the definition for
the imported TagDecl is complete.

 - Also, fix a refacto that left extra "all" component in list (this is now
   defined in the groups explicitly)
 - Reapply of r143879 now that Make should see needed deps.

dragonegg self-host buildbot will recover (it is complaining about object
files differing between different build stages).  Original commit message:

Add a hack to the scheduler to disable pseudo-two-address dependencies in
basic blocks containing calls. This works around a problem in which
these artificial dependencies can get tied up in calling seqeunce
scheduling in a way that makes the graph unschedulable with the current
approach of using artificial physical register dependencies for calling
sequences. This fixes PR11314.
