Justin Bogner 953e2407ed llvm-cov: Disentangle the coverage data logic from the display (NFC) 
This splits the logic for actually looking up coverage information
from the logic that displays it. These were tangled rather thoroughly
so this change is a bit large, but it mostly consists of moving things
around. The coverage lookup logic itself now lives in the library,
rather than being spread between the library and the tool.

Alex Lorenz e82d89cc37 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'.
