So far this was done by directly calling PM->getAnalysis() in create*Analysis().
But this required a correct order of analysis definitions in Analysis.def.

This allows one by editing one place to create an Analysis kind and ensure that
your analysis is properly registered in all of the relevant places for use with
swift/sil-opt.
If we add tools like a sil bugpoint, this will make it easy to add analysis
without having to know about all of these locations.
It also standardizes the create***Analysis API to take a SILModule and a
SILPassManager. All passes take in a SILModule and some take in a
SILPassManager. By standardizing the API and in the cases where SILPassManager
is not used, just making it a dead argument enables metaprogramming.

This commit splits DominanceAnalysis into two analysis (Dom and PDom) that
can be cached and invalidates using the common FunctionAnalysisBase interface
independent of one another.
Swift SVN r26643
This follows the model of dominance info and allows me to create reachability
methods on SILBasicBlock without creating dependencies from swiftSIL to
swiftSILAnalysis.
