John McCall b46f287e48 Clean up the sentinel-attribute checking code a lot. Document 
what 'nullPos' is supposed to mean, at least at this one site.
Use closed forms for the arithmetic.  Rip out some clever but
ultimately pointless code that was trying to use 0 or 0L depending
the size of a pointer vs. the size of int;  first, it didn't work
on LLP64 systems, and second, the sentinel checking code requires
a pointer-typed value anyway, so this fixit would not have actually
removed the warning.

John McCall 9c3467e26c Code formatting; no functionality change.

John McCall fec112d50e Contextually converting to 'id' is not a useful operation. Contextually 
converting to an arbitrary Objective-C pointer type is.  Without
significantly re-implementing anything, change the API to reflect this,
and as a minor optimization, strip the pointer conversion off before
potentially building it.

Mostly, this removes a really bizarre-looking bit of code from
BuildInstanceMessage.

John McCall 9320b87cff Give conversions of block pointers to ObjC pointers a different cast kind 
than conversions of C pointers to ObjC pointers.  In order to ensure that
we've caught every case, add asserts to CastExpr that strictly determine
which cast kind is used for which kind of bit cast.

Douglas Gregor bab8a96f2f Implement the Objective-C 'instancetype' type, which is an alias of 
'id' that can be used (only!) via a contextual keyword as the result
type of an Objective-C message send. 'instancetype' then gives the
method a related result type, which we have already been inferring for
a variety of methods (new, alloc, init, self, retain). Addresses
<rdar://problem/9267640>.

Richard Trieu aa5e256c20 Change the self-reference visitor (which gives the warning for self-reference oninitalization warning of -Wuninitialized) to exclude member variables that can decay into pointers. This will cause it to no longer warn on this code:

Fariborz Jahanian 5f2b703651 objc-gc: Don't force a __strong type'd property

probably be flagged as error - later to come.

Francois Pichet bcf6471010 In Microsoft mode, if we are inside a template class member function and we can't resolve a function call then create a type-dependent CallExpr even if the function has no type dependent arguments. The goal is to postpone name lookup to instantiation time to be able to search into type dependent base classes. 
With this patch in, clang will generate only 37 errors (down from 212) when parsing a typical MFC source file.
