[PM] Fold all three analysis managers into a single AnalysisManager

template.

This consolidates three copies of nearly the same core logic. It adds
"complexity" to the ModuleAnalysisManager in that it makes it possible
to share a ModuleAnalysisManager across multiple modules... But it does
so by deleting *all of the code*, so I'm OK with that. This will
naturally make fixing bugs in this code much simpler, etc.

The only down side here is that we have to use 'typename' and 'this->'
in various places, and the implementation is lifted into the header.
I'll take that for the code size reduction.

The convenient names are still typedef-ed and used throughout so that
users can largely ignore this aspect of the implementation.

The follow-up change to this will do the exact same refactoring for the
PassManagers. =D

It turns out that the interesting different code is almost entirely in
the adaptors. At the end, that should be essentially all that is left.
