Peter Collingbourne 9114759641 C1X: implement generic selections 
As an extension, generic selection support has been added for all
supported languages.  The syntax is the same as for C1X.

Sebastian Redl c17003c66b Create __has_feature(cxx_noexcept) and mark it as working. 
Find out that our C++0x status has only one field for noexcept expression and specification together, and that it was accidentally already marked as fully implemented.
This completes noexcept specification work.

Jeffrey Yasskin bbc4eea2c2 Revert r124217 because it didn't catch the actual error case it was trying to 
catch:

  lock_guard(my_mutex);

Jeffrey Yasskin 08a4f8f197 Add an attribute to forbid temporary instances of a type. This allows class 
authors to write 

  class __attribute__((forbid_temporaries)) Name { ... };

when they want to force users to name all variables of the type. This protects
people from doing things like creating a scoped_lock that only lives for a
single statement instead of an entire scope.

The warning produced by this attribute can be disabled by
-Wno-forbid-temporaries.

Alexis Hunt af4e28d897 Add a bunch more feature-checking macros for C++0x features. Some of these are

a thing to have them work when we implement the features.

Chris Lattner b6f77af532 implement and document a new __has_feature and __has_builtin magic 
builtin preprocessor macro.  This appears to work with two caveats:
1) builtins are registered in -E mode, and 2) target-specific builtins
are unconditionally registered even if they aren't supported by the
target (e.g. SSE4 builtin when only SSE1 is enabled).

Douglas Gregor 94349fd8cb Allow "overloadable" functions in C to be declared as variadic without 
any named parameters, e.g., this is accepted in C:

  void f(...) __attribute__((overloadable));

although this would be rejected:

  void f(...);

To do this, moved the checking of the "ellipsis without any named
arguments" condition from the parser into Sema (where it belongs anyway).
