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.

This debug output is really for testing CoverageMappingReader, not the
llvm-cov tool. Move it to where it can be more useful.

Having create* functions return the object they create is more
readable than using an in-out parameter.

The filename-equivalence flag allows you to show coverage when your
source files don't have the same full paths as those that generated
the data. This is mostly useful for writing tests in a cross-platform
way.
This wasn't triggering in cases where the filename was derived
directly from the coverage data, which meant certain types of test
case were impossible to write. This patch fixes that, and following
patches involve tests that need this.

- Replace std::unordered_map with DenseMap
- Use std::pair instead of manually combining two unsigneds
- Assert if insert is called with invalid arguments
- Avoid an unnecessary copy of a std::vector

This encapsulates how we handle the coverage regions of a file or
function. In the old model, the user had to deal with nested regions,
so they needed to maintain their own auxiliary data structures to get
any useful information out of this. The new API provides a sequence of
non-overlapping coverage segments, which makes it possible to render
coverage information in a single pass and avoids a fair amount of
extra work.

SourceCoverageView currently has "Kind" and a list of child views, all
of which must have either an expansion or an instantiation Kind. In
addition to being an error-prone design, this makes it awkward to
differentiate between the two child types and adds a number of
optionally used members to the type.
Split the subview types into their own separate objects, and maintain
lists of each rather than one combined "Children" list.

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.

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

This fixes a call to sys::fs::equivalent that should've been to
CodeCoverageTool::equivalentFiles, which lets us restore the test of
r217476 that was removed in r217478.
This reverts r217478, but the test works this time.

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.

This name was too similar to CoverageMappingRegion, and the type
really belongs in the coverage library anyway.

FunctionCoverageMapping::PrettyName was from a version of the tool
during review, and isn't actually used currently.

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'.
