cleans up and improves a few things: - We get rid of the ugly dance of computing all of the captures in data structures that clone those of CapturingScopeInfo, centralizing the logic for accessing/updating these data structures - We re-use the existing capture logic for 'this', which actually works now. Cleaned up some diagnostic wording in minor ways as well. llvm-svn: 149516
