Peter Collingbourne 9114759641 C1X: implement generic selections

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.

Peter Collingbourne 2f1e36bfd0 Rename tok::eom to tok::eod. 
The previous name was inaccurate as this token in fact appears at
the end of every preprocessing directive, not just macro definitions.
No functionality change, except for a diagnostic tweak.

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.
