9799cacba3 fatal error instead of ICE for impossible range during HIR lowering 
End-less ranges (`a...`) don't parse but bad syntax extensions could
conceivably produce them. Unbounded ranges (`...`) do parse and are
caught here.

The other panics in HIR lowering are all for unexpanded macros, which
cannot be constructed by bad syntax extensions.

69719df611 test inclusive ranges 
Mostly copy the tests from half-open ranges, adding some more for
DoubleEndedIterator and ExactSizeIterator.

Also thoroughly (I think) test that the feature gates are working.
