Alexander Kornienko 9a34889efe Added test with sizeof conditions (relies on to-be-implemented functionality of CFG, discussion: http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20120507/057370.html)

Alexander Kornienko 246e85ddb0 Don't offer '[[clang::fallthrough]];' fix-it when a fall-through occurs to a 
switch label immediately followed by a 'break;'.

Richard Smith 84837d5b5a Add -Wimplicit-fallthrough warning flag, which warns on fallthrough between 
cases in switch statements. Also add a [[clang::fallthrough]] attribute, which
can be used to suppress the warning in the case of intentional fallthrough.

Patch by Alexander Kornienko!

The handling of C++11 attribute namespaces in this patch is temporary, and will
be replaced with a cleaner mechanism in a subsequent patch.
