llvm-cov: Rename a variable and clean up its usage

Offset is a terrible name for an indentation / nesting level, and it
confuses me every time I look at this code.

llvm-cov: Make debug output more consistent

This changes the debug output of the llvm-cov tool to consistently
write to stderr, and moves the highlighting output closer to where
it's relevant.

llvm-cov: Fix an issue with showing regions but not counts

In r217746, though it was supposed to be NFC, I broke llvm-cov's
handling of showing regions without showing counts. This should've
shown up in the existing tests, except they were checking debug output
that was displayed regardless of what was actually output. I've moved
the relevant debug output to a more appropriate place so that the
tests catch this kind of thing.

llvm-cov: Clean up some redundancy in the view API (NFC)

This removes the need to pass a starting and ending line when creating
a SourceCoverageView, since these are easy to determine.

llvm-cov: Fix a misuse of ArrayRef::slice I introduced in r217430

It appears this code was completely untested, so using ArrayRef wrong
didn't break anything obvious.

llvm-cov: Combine two types that were nearly identical (NFC)

llvm-cov had a SourceRange type that was nearly identical to a
CountedRegion except that it shaved off a couple of fields. There
aren't likely to be enough of these for the minor memory savings to be
worth the extra complexity here.

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'.
