A single function in SourceCoverageDataManager was the only user of some of the comparisons in CounterMappingRegion, and at this point we know that only one file is relevant. This lets us use slightly simpler logic directly in the client. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@217745 91177308-0d34-0410-b5e6-96231b3b80d8
