Undo the fix for Trac #3772 and do it a new way
The main idea is that I'm now treating a single-method dictionary very
much like a multi-method dictionary. In particular, it respond to
exprIsConApp_maybe, even though newtypes aren't *really* proper
constructors.
See long comments with Note [Single-method classes] for why
this slight hack is justified.
