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.
