c++: TTP in member alias template [PR104107]

In the first testcase, coerce_template_template_parms was adding too much
of
outer_args when coercing to match P's template parameters, so that when
substituting into the 'const T&' parameter we got an unrelated template
argument for T.  We should only add outer_args when the argument template
is
a nested template.

gcc/cp/ChangeLog:

* pt.cc (coerce_template_template_parms): Take full parms.
Avoid adding too much of outer_args.
(coerce_template_template_parm): Adjust.
(template_template_parm_bindings_ok_p): Adjust.
(convert_template_argument): Adjust.

gcc/testsuite/ChangeLog:

* g++.dg/cpp0x/alias-decl-ttp2.C: New test.
* g++.dg/cpp1z/ttp2.C: New test.
