David Blaikie d937bf13d4 Adding FixIts to static/inline main declaration diagnostics.

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>.

Douglas Gregor af5c48490e Optimize the preprocessor's handling of the __import_module__ 
keyword. We now handle this keyword in HandleIdentifier, making a note
for ourselves when we've seen the __import_module__ keyword so that
the next lexed token can trigger a module import (if needed). This
greatly simplifies Preprocessor::Lex(), and completely erases the 5.5%
-Eonly slowdown Argiris noted when I originally implemented
__import_module__. Big thanks to Argiris for noting that horrible
regression!

Chandler Carruth 3d45b23dfc Extract the emission of the diagnostic's location into a separate 
function. This is really the beginning of the second phase of
refactorings here. The end goal is to have (roughly) three interfaces:

1) Base class to format a single diagnostic suitable for display on the
   console.
2) Extension of the base class which also displays a caret diagnostic
   suitable for display on the console.
3) An adaptor that implements the DiagnosticClient by delegating to #1
   and/or #2 as appropriate.

Once we have these, things like libclang's formatDiagnostic can use #1
and #2 to provide really well formatted (and consistently formatted!)
textual formatting of diagnostics.

Getting there is going to be quite a bit of shuffling. I'm basically
sketching out where the interface boundaries can be drawn for #1 and #2
within the existing classes. That lets me shuffle with a minimum of fuss
and delta. Once that's done, and any of the related interfaces that need
to change are updated, I'll hoist these into separate headers and
re-implement libclang in terms of their interfaces. Long WIP, but
comments at each step welcome. =D

Chandler Carruth 773757a962 Switch the CharSourceRange array to a small vector. The array was 
a stack array of a magical size with an assert() that we never
overflowed it. That seems incredibly risky. We also have a very nice API
for bundling up a vector we expect to usually have a small size without
loss of functionality or security if the size is excessive.

The fallout is to remove the last pointer+size parameter pair that are
traced through the recursive caret diagnostic emission.

Eli Friedman e9f8113ec4 Switch clang over to using fence/atomicrmw/cmpxchg instead of the intrinsics (which will go away). LLVM CodeGen does almost exactly the same thing with these and the old intrinsics, so I'm reasonably confident this will not break anything. 
There are still a few issues which need to be resolved with code generation for atomic load and store, so I'm not converting the places which need those for now.

I'm not entirely sure what to do about __builtin_llvm_memory_barrier: the fence instruction doesn't expose all the possibilities which can be expressed by __builtin_llvm_memory_barrier.  I would appreciate hearing from anyone who is using this intrinsic.

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.

Chandler Carruth 20bfaa0f68 Hoist the construction of the FixItHint line into a member function with 
a defined interface. This isn't as nice as the previous one, but should
get better as I push through better data types in all these functions.

Also, I'm hoping to pull some aspects of this out into a common routine
(such as tab expansion).

Again, WIP, comments welcome as I'm going through.

Douglas Gregor e0e9630e07 When extracting the callee declaration from a call expression, be sure 
to look through SubstNonTypeTemplateParmExprs. Then, update the IR
generation of CallExprs to actually use CallExpr::getCalleeDecl()
rather than attempting to mimick its behavior (badly).
