Once the issues are imported into a clean llvm-project-NEW repository,
push tags into it, manually* recreate github releases - why do their dates
matter? - by manually* re-uploading all the manually uploaded assets,
then lock down the old llvm-project, rename it to llvm-project-obsolete,
mirror it's branches into the new repo, and finally rename the new
llvm-project-NEW to llvm-project. And delete llvm-project-obsolete.
As far as git is concerned, by now llvm-project repo is exactly
identical as the old one.

The only casualties will be unimportant things:
github stars, github forks, github release dates;
but if github can't be bothered to help with those,
it will serve as a forever reminder to the users that github is unreliable,
and false dependence should not be created on replaceable unreliable things.

* Surely it can be automated.
