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'.

These inputs were pre-generated to allow for easier testing of llvm-cov.
The files used to test the gcov compatible code coverage tool were generated
using the following method:
test.gcno and test.gcda were create by running clang:
clang++ -g -ftest-coverage -fprofile-arcs test.cpp
test.cpp.gcov was created by running gcov 4.2.1:
gcov test.cpp
The 'covmapping' files that are used to test llvm-cov contain raw sections
with the coverage mapping data generated by the compiler and linker. They are
created by running clang and llvm-cov:
clang++ -fprofile-instr-generate -fcoverage-mapping -o test test.cpp
llvm-cov convert-for-testing -o test.covmapping test
The 'profdata' files were generated by running an instrumented version of the
program and merging the raw profile data using llvm-profdata.
./test
llvm-profdata merge -o test.profdata default.profraw
