Don't report errors if we don't have a correct type switch guard; instead ignore it and leave it to the type-checker to report the error. This leads to better error messages concentrating on the type switch guard rather than errors around (confusing) syntactic details. Also clean up some code setting up AssertExpr (they never have a nil Type field) and remove some incorrect TODOs. Fixes #24470.
