5a6edad3d8 llvm-cov: Return unique_ptrs instead of filling objects (NFC)
Having create* functions return the object they create is more
readable than using an in-out parameter.

116c16642d llvm-cov: Generalize -filename-equivalence
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.

1ae21d1367 llvm-cov: Simplify FunctionInstantiationSetCollector (NFC)
- 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

fe357c003f llvm-cov: Rework the API for getting the coverage of a file (NFC)
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.

5e1400a81c llvm-cov: Distinguish expansion/instantiation from SourceCoverageView
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.

92bb302314 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.

7dad93bec2 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.

3d7260e7b2 Revert "llvm-cov: Remove an overly system specific test"
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.

e53be0662a 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.

8e8aa3ff90 llvm-cov: Rename MappingRegion to coverage::CountedRegion (NFC)
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.

There's no ownership going on here, and no reason to heap allocate
this object.

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'.
