c++: templated static local var has value-dep addr [PR98930]

c++: templated static local var has value-dep addr [PR98930]

Here uses_template_parms returns false for the dependent type A<&impl::i>,
which causes tsubst_aggr_type to think it's non-dependent and not bother
substituting into it, leading to breakage.

This patch fixes this by making has_value_dependent_address also return
true for templated static local variables.

	PR c++/98930

	* pt.c (has_value_dependent_address): Return true for a static
