Subject: Do a better job at computing dead symbols.

Implemented support for better localized leaks in the CF reference count checker.
Now leaks should be flagged close to where they occur.

This should implement the desired functionality in <rdar://problem/5879592>, although the diagnostics still need to be improved.
