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'.

The gcov compatible code is moved to its own file and
llvm-cov is updated to be a wrapper that always calls
the gcov main function.

Add llvm-cov skeleton. It has initial support to read coverage info generated by GCOVProfiling.cpp.
Today, you can do
prompt> clang a.c -ftest-coverage -fprofile-arcs -o a
prompt> ./a
prompt> llvm-cov -gcno a.gcno -gcda a.gcda
