getFunctionLevelDeclContext needs to get the previous DeclContext if EnterDeclaratorContext has been called. Fixes PR4694. (Doug, please review)

instantiation, and fixes both PR3444 and <rdar://problem/6757457>.

Permit a class to friend its class members in C++ 98, as long as extensions
are enabled (and even when they aren't, only give an extwarn about it).
