r362119 - Add Attribute NoThrow as an Exception Specifier Type

I'm not sure this is the best fix. From the patch description, it sounds
like this is a Microsoft-specific change. So splitting this into a new
diag group that then everyone using the Microsoft headers has to disable
seems a bit roundabout – don't we get the same behavior by not emitting
this warning in the first place, except that we don't require everyone
using clang-cl to explicitly disable this warning then?
