Currently we run logspace tests for extensive tests, but there isn't any reason we couldn't also run more kinds of tests more extensively (e.g. more edge cases, combine edge cases with logspace for multi-input functions, etc). As a first step toward making this possible, make `extensive` a new field in `CheckCtx`, and rename `QuickSpaced` to `Spaced`.
