All those "Hearts <3 ♥︎ 💘" and "Café 🍵"s will be lost in time, like tears in rain?

@palimondo Gonna assume that's a joke that went over my head. If it's not, please try to explain.

That was a Blade Runner reference... and I was wondering if the removed documentation that was demonstrating use of Index with the "Hearts <3 ♥︎ 💘" and "Café 🍵"s would reappear in the new String.Index later, or was removed for good.

Oh, removed for good because these types and therefore overloads are collapsing with others. However I believe the same strings exist on the overloads with which they are collapsing, unless @natecook1000 was exceptionally, gratuitously creative ;-)

I take it back; @natecook1000 was creative with good reason and many of them do drop; He'll have to rewrite the docs for these things anyway.

Uh, right. The linux failure is because I took away some SPI that Foundation was using for the Linux case only. It's easy to bring back but I want to let the other tests finish so I didn't push it here.

Un-revert "[stdlib] String index interchange, etc." (#10812)
9159239 
I failed to merge the upstream changes to swift-corelibs-foundation at the same
time as I merged that #9806, and it broke on linux. Going to get it right this
time.
