Rework the Parser-Sema interaction for Objective-C message sends. Major changes include: - Expanded the interface from two actions (ActOnInstanceMessage, ActOnClassMessage), where ActOnClassMessage also handled sends to "super" by checking whether the identifier was "super", to three actions (ActOnInstanceMessage, ActOnClassMessage, ActOnSuperMessage). Code completion has the same changes. - The parser now resolves the type to which we are sending a class message, so ActOnClassMessage now accepts a TypeTy* (rather than an IdentifierInfo *). This opens the door to more interesting types (for Objective-C++ support). - Split ActOnInstanceMessage and ActOnClassMessage into parser action functions (with their original names) and semantic functions (BuildInstanceMessage and BuildClassMessage, respectively). At present, this split is onyl used by ActOnSuperMessage, which decides which kind of super message it has and forwards to the appropriate Build*Message. In the future, Build*Message will be used by template instantiation. - Use getObjCMessageKind() within the disambiguation of Objective-C message sends vs. array designators. Two notes about substandard bits in this patch: - There is some redundancy in the code in ParseObjCMessageExpr and ParseInitializerWithPotentialDesignator; this will be addressed shortly by centralizing the mapping from identifiers to type names for the message receiver. - There is some #if 0'd code that won't likely ever be used---it handles the use of 'super' in methods whose class does not have a superclass---but could be used to model GCC's behavior more closely. This code will die in my next check-in, but I want it in Subversion. llvm-svn: 102021
