c++: Clear uninstantiated template friend when instantiating [PR104234]
Otherwise attempting to get the originating module declaration ICEs
because the DECL_CHAIN of an instantiated friend template is no longer
its context.
PR c++/104234
PR c++/112580
gcc/cp/ChangeLog:
* pt.cc (tsubst_template_decl): Clear
DECL_UNINSTANTIATED_TEMPLATE_FRIEND_P.
gcc/testsuite/ChangeLog:
* g++.dg/modules/pr104234.C: New test.
