    Fix #14719 by using the setting the right SrcSpan · 59fa7b32
    Ryan Scott authored
    Currently, error messages that germane to GADT constructors
    put the source span at only the first character in the constructor,
    leading to insufficient caret diagnostics. This can be easily fixed
    by using a source span that spans the entire constructor, instead of
    just the first character.
    
    Test Plan: make test TEST=T14719
