its sentinel. This is quite a win when a function really has a basic block.                  
When the function is just a declaration (and stays so) the old way did not
allocate a sentinel. So this change is most beneficial when the ratio of
function definition to declaration is high. I.e. linkers etc. Incidentally  
these are the most resource demanding applications, so I expect that the
reduced malloc traffic, locality and space savings outweigh the cost of
addition of two pointers to Function.

Fix <rdar://problem/6619539> incompatible pointer types sending 'XCElementSpacer *', expected 'XCElement *' (not handling protocol signatures correctly?).

- Reworked ASTContext::canAssignObjCInterfaces().
- Added ObjCProtocolDecl::lookupProtocolNamed().

"This patch uses the new ObjCImplDecl class to merge  Sema::ImplMethodsVsClassMethods and Sema::ImplCategoryMethodsVsIntfMethods methods.
And now, when clang check a class implementation to find unimplemented methods, it also checks all methods from the class extensions (unnamed categories).

There is also a test case to check this warning.

This patch contains also a minor update for ObjCImplDecl . getNameAsCString and getNameAsString now returns an empty string instead of crashing for unnamed categories."
