John McCall 4d55f5a893 Don't warn about the 'extern' in 'extern "C"' on a tag decl. This is 
usually useless, but not always.

Douglas Gregor fceea36501 When checking whether to diagnose an initialized "extern" variable, 
look for the const on the base type rather than on the top-level
type. Fixes PR6495 properly.

Douglas Gregor c81ca09830 Disable the "'extern' variable has an initializer" warning in C++, 
since it makes sense there to have const extern variables. Fixes
PR6495.
