Teach llvm-cov to use the new llvm JSON library, and remove some
redundant/brittle JSON serialization tests.

llvm-cov tends to highlight too many regions because its policy is to
highlight all region entry segments. This can look confusing to users:
not all region entry segments are interesting and deserve highlighting.
Emitting these highlights only when the region count differs from the
line count is a more user-friendly policy.

Make sure that the text and html emitters always emit the same set of
region markers, and avoid emitting redundant markers for line segments
which don't end on the line they start on.
This is related to D35925, and depends on D36014

another machine to your local copies
Summary:
This patch adds the -path-equivalence option (example: llvm-cov show -path-equivalence=/origin/path,/local/path) which maps the source code path from one machine to another when using `llvm-cov show`. This is similar to the -filename-equivalence option, but doesn't require you to specify all the source files on the command line.
This allows you to generate the coverage data on one machine (e.g. in a CI system), and then use llvm-cov on another machine where you have the same code base on a different path.

This enables users to export coverage information as portable JSON for use by
analysis tools and storage in document based databases.
The export sub-command is invoked just like the others:
llvm-cov export -instr-profile path/to/foo.profdata path/to/foo.binary
The resulting JSON contains a list of files and functions. Every file object
contains a list of segments, expansions, and a summary of the file's region,
function, and line coverage. Every function object contains the function's name
and regions. There is also a total summary for the entire object file.
Changes since the initial commit (r276813):
- Fixed the regexes in the tests to handle Windows filepaths.

This reverts commit r276813. The Windows bots are complaining about some
of the filename regexes in the tests:

llvm-cov was truncating numbers that were larger than a particular
fixed width, which is as confusing as it is useless. Instead, we use
engineering notation with SI prefix for magnitude.

This still doesn't actually work correctly for big endian input files,
but since these tests all use little endian input files they don't
actually fail. I'll be committing a real fix for big endian soon, but
I don't have proper tests for it yet.

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.

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'.
