Chandler Carruth 9779830513 Move the HilightRange method from TextDiagnosticPrinter down to 
CaretDiagnostic. It's completely generic, with nothing to do with the
diagnostic client or info APIs.

Argyrios Kyrtzidis 7d500b3457 operator->() in PreprocessingRecord::iterator is useless since we

Eli Friedman e978d2f644 Relax the MemOperands on atomics a bit. Fixes -verify-machineinstrs failures for atomic laod/store on ARM. 
(The fix for the related failures on x86 is going to be nastier because we actually need Acquire memoperands attached to the atomic load instrs, etc.)

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.

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: 
struct foo { char a[100], *e; } bar = { .e = bar.a };

Fariborz Jahanian 5f2b703651 objc-gc: Don't force a __strong type'd property 
to be 'weak'. This prevents a crash and should 
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.

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).
