Change QuestionMark for better record field missing error message.
While we were adding a new field into `QuestionMark`, we
decided to go ahead and refactor the constructor to hold
an actual record. This record now holds the name, obligations, and
whether the evar represents a missing record field.
This is used to provide better error messages on missing record
fields.
