Summary:
This change equips lit.py with two new options, --num-shards=M and
--run-shard=N (set by default from env vars LIT_NUM_SHARDS and LIT_RUN_SHARD).
The options must be used together, and N must be in 1..M.
Together these options effect only test selection: they partition the testsuite
into M equal-sized "shards", then select only the Nth shard. They can be used
in a cluster of test machines to achieve a very crude (static) form of
parallelism, with minimal configuration work.

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.

Lots of blocks had "llvm" or "nasm" syntax types but either weren't following
the syntax, or the syntax has changed (and sphinx hasn't keep up) or the type
doesn't even exist (nasm?).
Other documents had :options: what were invalid. I only removed those that had
warnings, and left the ones that didn't, in order to follow the principle of
least surprise.
This is like this for ages, but the buildbot is now failing on errors. It may
take a while to upgrade the buildbot's sphinx, if that's even possible, but
that shouldn't stop us from getting docs updates (which seem down for quite
a while).
Also, we're not losing any syntax highlight, since when it doesn't parse, it
doesn't colour. Ie. those blocks are not being highlighted anyway.
I'm trying to get all docs in one go, so that it's easy to revert later if we
do fix, or at least easy to know what's to fix.

Add a "-j" option to llvm-profdata to control the number of threads used.
Auto-detect NumThreads when it isn't specified, and avoid spawning threads when
they wouldn't be beneficial.
I tested this patch using a raw profile produced by clang (147MB). Here is the
time taken to merge 4 copies together on my laptop:
No thread pool: 112.87s user 5.92s system 97% cpu 2:01.08 total
With 2 threads: 134.99s user 26.54s system 164% cpu 1:33.31 total
Changes since the initial commit:
- When handling odd-length inputs, call ThreadPool::wait() before merging the
last profile. Should fix a race/off-by-one (see r275937).

The default behavior of bugpoint is to print "<crash>" when it finds a reduced
test that crashes compilation. With this flag we now can see the output of the
crashing program. This is useful to make sure it is the same error being
tracked down and not a different error that happens to crash the compiler as
well.

Add an option to specify a symbol demangler (as well as options to the
demangler). This can be used to make reports more human-readable.
This option is especially useful in -output-dir mode, since it isn't as
easy to manually pipe reports into a demangler in this mode.

Passing -output-dir path/to/dir to llvm-cov show creates path/to/dir if
it doesn't already exist, and prints reports into that directory.
In function view mode, all views are written into
path/to/dir/functions.$EXTENSION. In file view mode, all views are
written into path/to/dir/coverage/$PATH.$EXTENSION.
Changes since the initial commit:
- Avoid accidentally closing stdout twice.

Changes since the initial commit:
- Normalize file paths read from the file to prevent Windows path
separators from escaping parts of the path.
- Since we need to store the normalized file paths in WeightedFile,
don't do tricky things to keep the source MemoryBuffer alive.
- Don't use list-initialization for a std::string in WeightedFile.
