Apologies for the reading comprehension failure.

The SemaCXX/warn-consumed-parsing.cpp does have some of the tests I
was looking for (it's missing ones for constructors and destructors),
and brings up an improvement I'd like to see (at some point):

void function0(void) CONSUMES; // expected-warning {{'consumes'
attribute only applies to methods}}

This is a very confusing warning for the user since the attribute is
applied to a method.  I think warn_attribute_wrong_decl_type and
err_attribute_wrong_decl_type should have a new field for instance
methods (or are static member functions also acceptable?).

Thanks!
