c++: compound-requirement partial substitution [PR113966]
When partially substituting a requires-expr, we don't want to perform
any additional checks beyond the substitution itself so as to minimize
checking requirements out of order. So don't check the return-type-req
of a compound-requirement during partial substitution. And don't check
the noexcept condition either since we can't do that on templated trees.
PR c++/113966
gcc/cp/ChangeLog:
* constraint.cc (tsubst_compound_requirement): Don't check
the noexcept condition or the return-type-requirement when
partially substituting.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/concepts-friend17.C: New test.
