Char: delete bitwise operator methods for Char type

[StefanKarpinski]

Alternative to #11103 – just delete them all.

+1, but probably a deprecation phase wouldn't hurt?

[StefanKarpinski]

Yes, was going to add those pending the outcome of the discussion on #11103. Also, it's kind of good to go through CI without deprecations first to make sure you didn't miss any usages in tests that are hidden by having the deprecation definitions. It's happened a few times that we've discovered lingering usages that only break when we delete the deprecations.

Good idea. Best to mark as WIP at that stage then?

+1, retaining these was an oversight of makingChar !<: Integer.

@StefanKarpinski What all does CI do, in addition to Base.runtests()? I've been always doing that before pushing to GitHub... and I already had done Base.runtests() with all of the bitwise operators totally removed... Thanks!

[StefanKarpinski]

It does that but on many platforms. Probably overkill in this case, admittedly.

[ScottPJones]

Could you merge this in to Base, and then close #11103? Since this handles the not logical bitwise operations that I'd removed as part of #11103, I'm happy to just leave it at that...
