Hi!
The recent change to move the warning about misplaced attributes resulted
in ICE on the following testcase. The problem is that the ENUMERAL_TYPE
doesn't have type lang specific initialized and so
CLASSTYPE_TEMPLATE_INSTANTIATION macro segfaults.
Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux,
ok for trunk/4.7.1?

* decl.c (check_tag_decl): Only use CLASSTYPE_TEMPLATE_INSTANTIATION
on CLASS_TYPE_P types.
