If we only delete lines that are outer block statements (if, while, etc),
clang-format-diff.py can't format the statements inside the block statements.
An example to repro:
1. Delete the if statment at line 118 in llvm/lib/CodeGen/Analysis.cpp.
2. Run `git diff -U0 --no-color HEAD^ | clang/tools/clang-format/clang-format-diff.py -i -p1`
It fails to format the statement after if.

I find as I develop I'm moving between many different languages C++,C#,JavaScript all the time. As I move between the file types I like to keep `clang-format` as my formatting tool of choice. (hence why I initially added C# support in {D58404}) I know those other languages have their own tools but I have to learn them all, and I have to work out how to configure them, and they may or may not have integration into my IDE or my source code integration.
I am increasingly finding that I'm editing additional JSON files as part of my daily work and my editor and git commit hooks are just not setup to go and run [[ https://stedolan.github.io/jq/ | jq ]], So I tend to go to [[ https://jsonformatter.curiousconcept.com/ | JSON Formatter ]] and copy and paste back and forth. To get nicely formatted JSON. This is a painful process and I'd like a new one that causes me much less friction.
This has come up from time to time:

https://stackoverflow.com/questions/35856565/clang-format-a-json-filehttps://bugs.llvm.org/show_bug.cgi?id=18699
I would like to stop having to do that and have formatting JSON as a first class clang-format support `Language` (even if it has minimal style settings at present).
This revision adds support for formatting JSON using the inbuilt JSON serialization library of LLVM, With limited control at present only over the indentation level
This adds an additional Language into the .clang-format file to separate the settings from your other supported languages.

Different distributions have different strategies migrating the `python` symlink. Debian and its derivatives provide `python-is-python2` and `python-is-python3`. If neither is installed, the user gets no `/usr/bin/python`. The clang-format-diff script and consequently `arc diff` can thus fail with a python not found error. Since we require python greater than 3.6 as part of llvm prerequisites (https://llvm.org/docs/GettingStarted.html#software), let's go ahead and update this shebang.

Previously if we couldn't run the clang-format command
for some reason, you'd get an unhelpful error message:
```
OSError: [Errno 2] No such file or directory
```
Which doesn't tell you what was happening to cause this.
Catch the error and add the command we were attempting to run:
```
RuntimeError: Failed to run "<...>/clang-food <...>" - No such file or directory"
RuntimeError: Failed to run "<...>/clang-format <...>" - Permission denied"
```

Summary:
Add --relative to the suggested git-diff one liner. If the user does not
pass this argument, then git will produce a diff with the path relative
to the repository root. If the user's working directory is not the
repository root, then clang-format will complain that the file is not
found. The --relative argument makes git produce a diff with the files
relative to the working directory.
Add note to doc string to warn users about the fact that filenames
embedded in the diff are used as-is with no attempts to "do what they
mean, not what they say"

The python documentation says "it’s highly recommended that you use raw strings for all but the simplest expressions." (https://docs.python.org/3/library/re.html)
So do that with the attached patch generated by
sed -i -e "s/re.search('/re.search(r'/g" $(git grep -l 're.search(')
The warning can be seen in e.g. python3.7:
$ python3.7 -Wd

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

While debating the finer points of file extension matching, we somehow missed
the bigger problem that the current code will match anything starting with the
default or user-specified pattern (e.g. lit.site.cfg.in).
Fix this by doing what find(1) does, implicitly wrapping the pattern with ^$.

Add support for more filename extensions based on the list in the clang

Also adds a -regex option so users can override defaults if they have unusual
file extensions or want to format everything in the diff.
Keeping with tradition the flag is modelled on Unix conventions, this time
matching the semantics of find(1).

Also let clang-format-diff.py detect errors based on clang-format's
return code. Otherwise messages like "Can't find usable .clang-format,
falling back to LLVM style" can make it fail, which might be undesired.

Patch by Alp Toker. Many thanks!
Original descriptions:
clang-format-diff incorrectly modifies unchanged lines due to an error
in diff parsing.
The unified diff format has a default line change count of 1, and 0 may
be specified to indicate that no lines have been added. This patch
updates the parser to accurately reflect the diff specification.
This also has the benefit of stabilising the operation so it will
produce the same output when run multiple times on the same changeset,
which was previously not the case.
No tests added because this script is not currently tested (though we
should look into that!)
