Alex Lorenz f3efd69574 [ObjC] Make sure that the implicit arguments for direct methods have been setup ...

This commit sets the Self and Imp declarations for ObjC method declarations,
in addition to the definitions. It also fixes
a bunch of code in clang that had wrong assumptions about when getSelfDecl() would be set:

- CGDebugInfo::getObjCMethodName and AnalysisConsumer::getFunctionName would assume that it was
  set for method declarations part of a protocol, which they never were,
  and that self would be a Class type, which it isn't as it is id for a protocol.

Also use the Canonical Decl to index the set of Direct methods so that
when calls and implementations interleave, the same llvm::Function is
used and the same symbol name emitted.
