GCOV provides an option to prepend output file names with the source file name, to disambiguate between covered data that's included from multiple sources. Add a flag to llvm-cov that does the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207035 91177308-0d34-0410-b5e6-96231b3b80d8
