      Fix a wibble in default-type setting for TH
	-------------------------------------

When a bunch of declarations contains no 'default' declaration,
we were setting 'defaultDefaultTys' as appropriate default types.
This isn't right for Template Haskell, which may have more than
one bunch of top-level decls.  (The bunches are separated by
top-level declaration splices.)

Instead, if there is no 'default' declaration we should do nothing.
