c++: lambda in concept [PR105652]
We currently check satisfaction in the context of the constrained
declaration (which may be wrong, see PR104111). When checking C<int>
for S<int>, we currently substitute into the lambda in the context of
S<T> (rather than S<int>, which seems wrong if the above isn't wrong), so
the new closure type thinks its context is S<T>, which confuses debug
output. For the moment, let's work around all of this by overriding the
context of the closure.
PR c++/105652

* pt.cc (tsubst_lambda_expr): Don't let a namespace-scope lambda
instantiate into a class-scope lambda.

* g++.dg/cpp2a/concepts-lambda20.C: New test.
