In Objective-C, pull arbitrary attributes from overridden
...
methods, including indirectly overridden methods like those
declared in protocols and categories. There are mismatches
that we would like to diagnose but aren't yet, but this
is fine for now.
I looked at approaches that avoided doing this lookup
unless we needed it, but the infer-related-result-type
checks were doing it anyway, so I left it with the same
fast-path check for no previous declartions of that
selector.

Begin reworking static analyzer support for C++ method calls. The current logic was divorced
...
from how we process ordinary function calls, had a tremendous about of redundancy, and relied
strictly on inlining behavior (which was incomplete) to provide semantics instead of falling
back to the conservative analysis we use for C functions. This is a significant step into
making C++ analyzer support more useful.
