Artificial source test case

In 90333 there's a discussion of where attributes on lambdas should be
processed.  In 8.3 they were handled after the declarator but that regresse=
d in
9.  90333 says that it was fixed to work properly after the declarator and =
that
they also added support for attributes before the declarator.  However in
testing against 9.3 attributes after the declarator do not work so it does =
not
look like the fix is working.

cppreference says that lambda attributes should come after the declarator.=
=20
Testing with godbolt it looks like attributes after the declarator are the
common case (for example clang works on the test case and fails with attrib=
utes
before the declarator).=
