swiftlang/swift#19213 will change the internal layout of Set/Dictionary. Prepare for this by adding lldb support for the new storage layouts.

Bonus change: fix the new synthetic children frontend so that enumerating all children takes linear time. (It was quadratic with the old formatters.)

Feel free to remove the old layout. swiftc and swift-lldb are revlocked so keeping around legacy is pointless for now.

Cool, I will do that in a followup next week. (I kept support for the old stuff in case we need to temporarily take out the Set/Dictionary PR.)
