bb64afcc39 Diagnose attempts to declare a non-static data member with a 
non-identifier name. Fixes PR10839.

f937c023bf Rename TagDecl::isDefinition -> isCompleteDefinition 
for better self-documenting code, since the semantics
are subtly different from getDefinition().

0dfb889575 Support for C1x _Atomic specifier (see testcase). This is primarily being committed at the moment to help support C++0x <atomic>, but it should be a solid base for implementing the full specification of C1x _Atomic. 
Thanks to Jeffrey Yasskin for the thorough review!

43a87fe86a PR11067: A definition of a constexpr static variable doesn't need an initializer if the in-class declaration had one. Such a declaration must be initialized by a constant expression.

485b80fecc OpenCL: add a non-standard extension, cl_clang_storage_class_specifiers, 
which enables support for C99 storage-class specifiers.

This extension is intended to be used by implementations to implement
OpenCL C built-in functions.

b8c3aaf479 Allow getting all source locations of selector identifiers in a ObjCMethodDecl. 
Instead of always storing all source locations for the selector identifiers
we check whether all the identifiers are in a "standard" position; "standard" position is

  -Immediately before the arguments: -(id)first:(int)x second:(int)y;
  -With a space between the arguments: -(id)first: (int)x second: (int)y;
  -For nullary selectors, immediately before ';': -(void)release;

In such cases we infer the locations instead of storing them.

eb3c10c248 constexpr: semantic checking for constexpr functions and constructors. Based in 
part on patches by Peter Collingbourne.

We diverge from the C++11 standard in a few areas, mostly related to checking
constexpr function declarations, and not just definitions. See WG21 paper
N3308=11-0078 for details.

Function invocation substitution is not available in this patch; constexpr
functions cannot yet be used from within constant expressions.

32f5fe1467 Add explicit attributes to mark functions as having had their 
CoreFoundation object-transfer properties audited, and add a #pragma
to cause them to be automatically applied to functions in a particular
span of code.  This has to be implemented largely in the preprocessor
because of the requirement that the region be entirely contained in
a single file;  that's hard to impose from the parser without registering
for a ton of callbacks.

2316cd8b79 constexpr: semantic checking for constexpr variables. 
We had an extension which allowed const static class members of floating-point type to have in-class initializers, 'as a C++0x extension'. However, C++0x does not allow this. The extension has been kept, and extended to all literal types in C++0x mode (with a fixit to add the 'constexpr' specifier).
