add asNonNullable() to existing type infos

This adds code to ignore trailing `?` in `as` and `is` expressions
because the trailing `?` may be part of the larger expression.
At the moment, this change is a no-op, but will become active
when a subsequent CL lands support for nullable types as part of
https://github.com/dart-lang/language/issues/110
