The following invalid testcase triggers a broken diagnostic on mainline:
===================================
template<int> void foo()
{
__is_class(int)();
}
===================================
bug.cc: In function 'void foo()':
bug.cc:3: error: '#'trait_expr' not supported by dump_expr#<expression error>'
cannot be used as a function
This is similar to PR33212, but not yet fixed.
