c++/modules: imported spec befriending class tmpl [PR114889]
When adding to CLASSTYPE_BEFRIENDING_CLASSES as part of installing an
imported class definition, we need to look through TEMPLATE_DECL like
make_friend_class does.
Otherwise in the below testcase we won't add _Hashtable<int, int> to
CLASSTYPE_BEFRIENDING_CLASSES of _Map_base, which leads to a bogus
access check failure for _M_hash_code.
PR c++/114889
gcc/cp/ChangeLog:
* module.cc (trees_in::read_class_def): Look through
TEMPLATE_DECL when adding to CLASSTYPE_BEFRIENDING_CLASSES.
gcc/testsuite/ChangeLog:
* g++.dg/modules/friend-8_a.H: New test.
* g++.dg/modules/friend-8_b.C: New test.
