Make sure we properly treat names defined inside a block as local names. There are basically three fixes here. One, correctly treat blocks as a context where we need to use local-name mangling using the new isLocalContainerContext helper. Two, make CXXNameMangler::manglePrefix handle local names in a consistent way. Three, extend CXXNameMangler::mangleLocalName so it can mangle a block correctly. llvm-svn: 185450
