Jordan Rose e723a27ffe -Warc-repeated-use-of-weak: look through explicit casts on assigned values. 
Reading from a weak property, casting the result, and assigning to a
strong pointer should still be considered safe.

Jordan Rose 62b379873d Pull ScopeInfo implementation into its own file. 
The infrastructure for -Warc-repeated-use-of-weak got a little too heavy
to leave sitting at the top of Sema.cpp.

No functionality change.
