[PATCH] D150990: [split-file] Add flags to support comments and adding extension to output files

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

Thanks for the reply. The motivation looks good!

> Those two features allow us to integrate split-file notation and C++ DR tests notation:
> // dr164: 16 becomes //--- dr164: 16, which produces dr164.cpp file with the corresponding test.
> I go into more details on motivation in Discourse thread.

I think this paragraph can be made clearer without being overly verbose:

We will change some tests under `clang/test/CXX/drs` to use `//--- dr164: 16` instead of `// dr164`.
With `--add-file-extension=.cpp --allow-comments`, split-file will create a file named `dr164.cpp` instead of `dr164: 16`.
