Ted Kremenek 25c1d57fc9 Teach -Wuninitialized to recognize common "noreturn" idioms in 
Objective-C related to NSException.

Fixes <rdar://problem/12287498>

I debated whether or not this logic should be sunk into the CFG
itself.  It's not clear if we should, as different analyses may
wish to have different policies.  We can re-evaluate this in the
future.

David Blaikie 4f4f349208 Show either a location or a fixit note, not both, for uninitialized variable warnings.

Chandler Carruth f04eb2de1f Now that the analyzer is distinguishing between uninitialized uses that 
definitely have a path leading to them, and possibly have a path leading
to them; reflect that distinction in the warning text emitted.

Ted Kremenek 908c09f64e Take 2: merge -Wuninitialized-experimental into -Wuninitialized. Only *must-be-uninitialized* warnings are reported, with *maybe-uninitialized* under a separate flag. I await any fallout/comments/feedback, although hopefully this will produce no noise for users.

Ted Kremenek 1b52844501 Move uninitialized variable checking back under -Wuninitialized-experimental. It is clear from user feedback that this warning is not quite ready.

Ted Kremenek 609e317084 Based on user feedback, swap -Wuninitialized diagnostics to have the warning refer to the bad use, and the note to the variable declaration.
