Alex Lorenz 6c7a6a1ba2 llvm-cov: add code coverage tool that's based on coverage mapping format and clang's pgo.
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'.
