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."

stripped .bc file, it didn't make any attempt to try to reuse anonymous types.
This causes an amazing type explosion due to types getting duplicated everywhere
they are referenced and other problems.

This also caused correctness issues, because opaque types are unique for each time
they are uttered in the file.  This means that stripping a .bc file could produce
a .ll file that could not be assembled (e.g. 2009-02-28-StripOpaqueName.ll).

This patch fixes both of these issues.
