reboot #5427 by @WalterBright as it is required for the new mangling in dlang/dmd#6998

Maybe something else changes, but locally I cannot reproduce an error with toDelegate!(void function(FreeListRef!(shared(int), true), int delegate(int, int) pure nothrow @nogc @safe, int, int) nothrow @nogc @system) as in the previous attempts build logs.

Did you see what were the mismatching commits?

Sorry, didn't note them down.

Previous working theory was that this only occurred after a force push (where it showed the pre- and post-force-push commits), but if it happened even if the branch wasn't updated since it was created, that's curious.

Oh, I'm guessing that might be related to that this PR has the exact same commits as another PR. Might be worth trying to rebase before opening a new PR.
