e109a2ca59 Attach class template attributes to the templated CXXRecordDecl, 
instead of silently discarding them.

As a side effect, this improves diagnostics for constexpr class
templates slightly.

fbf8752597 When performing name lookup for the previous declaration of a field, 
be sure to consider all of the possible lookup results. We were
assert()'ing (but behaving correctly) for unresolved values. Fixes

fe2750db42 Add -Wc++98-compat diagnostics for jumps which bypass initialization of non-POD 
but trivially constructible and destructible variables in C++11 mode. Also
incidentally improve the precision of the wording for jump diagnostics in C++98
mode.

f4ef4d2ec5 There's no point in marking a declaration invalid just because it 
shadows a template parameter. Complain about the shadowing (or not,
under -fms-extensions), but don't invalidate the declaration. Merely
forget about the template parameter declaration.

85308c6ecd Add typo correction for type names. 
The main motivation was to do typo correction in C++ "new" statements,
though picking it up in other places where type names are expected was
pretty much a freebie.

caf3390d44 Constant expression evaluation refactoring: 
- Remodel Expr::EvaluateAsInt to behave like the other EvaluateAs* functions,
   and add Expr::EvaluateKnownConstInt to capture the current fold-or-assert
   behaviour.
 - Factor out evaluation of bitfield bit widths.
 - Fix a few places which would evaluate an expression twice: once to determine
   whether it is a constant expression, then again to get the value.

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).
