swift-mirror/lib/SILAnalysis/ARCAnalysis.cpp
Michael Gottesman edab72fd4c [arc-opts] Teach ARC about when some instructions don't decrement ref counts. 
Specifically we teach ARC:

1. StrongPin never decrements ref counts.
2. CheckedCastAddrBranchInst only decrements ref counts if we are taking the
   source value.
