Vedant Kumar 7101d73c71 Retry: [llvm-cov] Add support for exporting coverage data to JSON
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:

Vedant Kumar f9151b9372 [llvm-cov] Separate presentation logic from formatting logic, NFC
This makes it easier to add renderers for new kinds of output formats.

- Define and document a pure-virtual coverage rendering interface.
- Move the text-based rendering logic into its a new file.
- Re-work the API to better reflect the presentation/formatting split.

Justin Bogner f91bc6cdd8 llvm-cov: Simplify coverage reports, fixing PR22575 in the process
PR22575 occurred because we were unsafely storing references into a
std::vector. If the vector moved because it grew, we'd be left
iterating through garbage memory. This avoids the issue by simplifying
the logic to gather coverage information as we go, rather than storing
it and iterating over it.

I'm relying on the existing tests showing that this is semantically
NFC, since it's difficult to hit the issue this fixes without
relatively large covered programs.

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'.

Alex Lorenz 2b5d03ae94 llvm-cov: move the gcov code into a separate file.
The gcov compatible code is moved to its own file and
llvm-cov is updated to be a wrapper that always calls
the gcov main function.

Devang Patel 3714065a94 Introduce llvm-cov.
Add llvm-cov skeleton. It has initial support to read coverage info generated by GCOVProfiling.cpp. 
Today, you can do
prompt> clang a.c -ftest-coverage -fprofile-arcs -o a
prompt> ./a
prompt> llvm-cov -gcno a.gcno -gcda a.gcda
