Teach the type-id/expression disambiguator about different
disambiguation contexts, so that we properly parse template arguments
such as
A<int()>
as type-ids rather than as expressions. Since this can be confusing
(especially when the template parameter is a non-type template
parameter), we try to give a friendly error message.
Almost, eliminate a redundant error message (that should have been a
note) and add some ultra-basic checks for non-type template
arguments.
