llvm-cov had a SourceRange type that was nearly identical to a CountedRegion except that it shaved off a couple of fields. There aren't likely to be enough of these for the minor memory savings to be worth the extra complexity here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@217417 91177308-0d34-0410-b5e6-96231b3b80d8
