As noted in https://reviews.llvm.org/D86137#2460135 parsing of
the clang-format parameter -Wno-error=unknown fails.
This currently is done by having `-Wno-error=unknown` as an option.
In this patch this is changed to make `-Wno-error=` parse an enum into a bit set.
This way the parsing is fixed and also we can possibly add new options easily.

`SourceManager::createFileID` asserts that the given `FileEntry` is not
null, so remove the logic that passed in `nullptr`. Since we just added
the file to an in-memory FS via an API that cannot fail, use
`llvm_unreachable` on the error path. Didn't use an `assert` since it
seems cleaner semantically to check the error (and better,
hypothetically, for updating the API to use `Expected` instead of
`ErrorOr`).
I noticed this incidentally while auditing calls to `createFileID`.
Currently newer clang-format options cannot be included in .clang-format files, if not all users can be forced to use an updated version.
This patch tries to solve this by adding an option to clang-format, enabling to ignore unknown (newer) options.

relative to the working directory.

Summary:
The current clang-format.py does not handle trailing newlines at the end of a file correctly.
Trailing empty lines get removed except one.
As far as I understand this is because clang-format gets fed from stdin and writes to stdout when called from clang-format.py.
In a "normal" file (with no trailing empty lines) the string that gets passed to clang-format does not contain a trailing '\n' after the '\n'.join from python.
The clang-format binary does not add a trailing newline to input from stdin, but (if there are multiple trailing '\n', all except one get removed).
When reading back this means that we see in python from a "normal" file a string with no trailing '\n'. From a file with (potentially multiple) empty line(s) at the end, we get a string with one trailing '\n' back in python. In the former case all is fine, in the latter case split('\n') makes one empty line at the end of the file out of the clang-format output. Desired would be instead that the **file** ends with a newline, but not with an empty line.
For the case that a user specifies a range to format (and wants to keep trailing empty lines) I did **not** try to fix this by simply removing all trailing newlines from the clang-format output. Instead, I add a '\n' to the unformatted file content (i.e. newline-terminate what is passed to clang-format) and then strip off the last newline from the output (which itself is now for sure the newline termination of the clang-format output).
(Should this get approved, I'll need someone to help me land this.)

While the actual mapping a user might want to use may well differ from my suggestion, I think it's nice to show the python2 and python3 version, such that a user can pick from the suggestions instead of googeling the python3 replacement for `:pyf` which they might not be familiar with.

On seeing a quote on twitter by @invalidop
> If it's not formatted with clang-format it's a build error.
This made me want to change the way I use clang-format into a tool that could optionally show me where my source code violates clang-format syle.
When I'm making a change to clang-format itself, one thing I like to do to test the change is to ensure I didn't cause a huge wave of changes, what I want to do is simply run this on a known formatted directory and see if any new differences arrive in a manner I'm used to.
This started me thinking that we should allow build systems to run clang-format on a whole tree and emit compiler style warnings about files that fail clang-format in a form that would make them as a warning in most build systems and because those build systems range in their construction I don't think its unreasonable to NOT expect them to have to do the directory searching or parsing the output replacements themselves, but simply transform that into an error code when there are changes required.
I am starting this by suggesing adding a -n or -dry-run command line argument which would emit a warning/error of the form
Support for various common compiler command line argumuments like '-Werror' and '-ferror-limit' could make this very flexible to be integrated into build systems and CI systems.
```

Summary:
This revision adds basic support for formatting C# files with clang-format, I know the barrier to entry is high here so I'm sending this revision in to test the water as to whether this might be something we'd consider landing.
Tracking in Bugzilla as:
https://bugs.llvm.org/show_bug.cgi?id=40850
Justification:
C# code just looks ugly in comparison to the C++ code in our source tree which is clang-formatted.
I've struggled with Visual Studio reformatting to get a clean and consistent style, I want to format our C# code on saving like I do now for C++ and i want it to have the same style as defined in our .clang-format file, so it consistent as it can be with C++. (Braces/Breaking/Spaces/Indent etc..)
Using clang format without this patch leaves the code in a bad state, sometimes when the BreakStringLiterals is set, it fails to compile.
Mostly the C# is similar to Java, except instead of JavaAnnotations I try to reuse the TT_AttributeSquare.
Almost the most valuable portion is to have a new Language in order to partition the configuration for C# within a common .clang-format file, with the auto detection on the .cs extension. But there are other C# specific styles that could be added later if this is accepted. in particular how `{ set;get }` is formatted.

We understand that people may be surprised that we're moving the header

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
