This commit expands llvm-cov's functionality by adding support for a new code coverage tool that uses LLVM's coverage mapping format and clang's instrumentation based profiling. The gcov compatible tool can be invoked by supplying the 'gcov' command as the first argument, or by modifying the tool's name to end with 'gcov'.
