c++: nested lambda capture pack [PR119345]
tsubst_stmt already registers a local capture proxy as a
local_specialization of both an outer capture proxy and the captured
variable; we also need to do that in add_extra_args.
PR c++/119345
gcc/cp/ChangeLog:
* pt.cc (add_extra_args): Also register a specialization
of the captured variable.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/lambda-targ14.C: New test.
