Implement caching of copy assignment operator lookup.

I believe, upon, careful review, that this code causes us to incorrectly handle exception specifications of copy assignment operators in C++03 mode. However, we currently do not seem to properly implement the subtle distinction between copying of members and bases made by implicit copy constructors and assignment operators in C++03 - namely that they are limited in their overload selection - in all cases. As such, I feel that committing this code is correct pending a careful review of our implementation of these semantics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@132841 91177308-0d34-0410-b5e6-96231b3b80d8
