Patch: PR c++/28114: Check for error_mark_node

This patch checks to see if pushdecl_with_scope returned an
error_mark_node and does an early return if it gets one.  This avoids
the ICE.  It does not change the error messages that are put out though.

y.C:1: error: template class without a name
y.C:1: error: types may not be defined in parameter types
y.C:5: error: conflicting declaration 'struct<anonymous>'
y.C:5: error: 'struct<anonymous>' has a previous declaration as 'struct<anonymou
y.C: In function 'void bar()':
y.C:5: error: no matching function for call to 'foo(int)'

OK to checkin?
