Based on groundwork by @natecook1000

Not yet ready for commit until we figure out the source compatibility/migration story.

Tests are mostly fixed up, except for things like hard-coded mangled name tests.

Range and ClosedRange have custom iterator types now to work around some issues that seem to be related to conditional conformance, but might also bring some perf wins.

Don't we still need this logic for the same-type initialisers (i.e Range's init(_: Range) & ClosedRange's init(_: ClosedRange))? Otherwise we'd be decrementing the upper bound in those cases. Or is the plan to get rid of the same-type initialisers?

Yeah, this looks like a meta programming fail on my part. I'm going to de-gyb the whole thing in the next push.

There's no reason to do a Range.init from a Range, in fact. It should just be a deprecation warning (for people who were using it to convert the now-typealiased CountableRange into a Range).
