Introduce __has_extension macro
...
__has_extension is a function-like macro which takes the same set
of feature identifiers as __has_feature. It evaluates to 1 if the
feature is supported by Clang in the current language (either as a
language extension or a standard language feature) or 0 if not.
At the same time, add support for the C1X feature identifiers
c_generic_selections (renamed from generic_selections) and
c_static_assert, and document them.
Patch by myself and Jean-Daniel Dupas.

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.
