Currently, llvm-cov isn't command-line compatible with gcov, which accepts a source file name as its first parameter and infers the gcno and gcda file names from that. This change keeps our -gcda and -gcno options available for convenience in overriding this behaviour, but adds the required parameter and inference behaviour as a compatible default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200417 91177308-0d34-0410-b5e6-96231b3b80d8
