- Move Sema::ObjCQualifiedIdTypesAreCompatible(), Sema::QualifiedIdConformsQualifiedId(), and a couple helper functions to ASTContext.
- Change ASTContext::canAssignObjCInterfaces() to use ASTContext:: ObjCQualifiedIdTypesAreCompatible(). 
- Tweak several test cases to accommodate the new/improved type checking.

out of memory, and also make the default memory manager allocate more memory
when it runs out.

Also, switch function stubs and global data over to using the BumpPtrAllocator.

This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB
of memory, and instead allocates in 512K slabs.  I suspect this size could go
lower, especially on embedded platforms, now that more slabs can be allocated.

These changes are necessary since I have plans to use this allocator in the JIT
memory manager, and it needs a special allocator.

I also added some tests which helped me pinpoint some bugs.

value.  This is on by default, and controlled by -Wreturn-type (-Wmost
-Wall).  I believe there should be very few false positives, though
the most interesting case would be:

  int() { bar(); }

when bar does:

  bar() { while (1) ; }

Here, we assume functions return, unless they are marked with the
noreturn attribute.  I can envision a fixit note for functions that
never return normally that don't have a noreturn attribute to add a
noreturn attribute.

If anyone spots other false positives, let me know!

templates, e.g.,

  template<typename T>
  struct Outer {
    struct Inner;
  };

  template<typename T>
  struct Outer<T>::Inner {
    // ...
  };

Implementing this feature required some extensions to ActOnTag, which
now takes a set of template parameter lists, and is the precursor to
removing the ActOnClassTemplate function from the parser Action
interface. The reason for this approach is simple: the parser cannot
tell the difference between a class template definition and the
definition of a member of a class template; both have template
parameter lists, and semantic analysis determines what that template
parameter list means.

There is still some cleanup to do with ActOnTag and
ActOnClassTemplate. This commit provides the basic functionality we
need, however.
