PR c++/54875 -  Error with alias template that resolves to an enum

Consider this short example:

     1 template<typename T>
     2 using AddConst = T const;
     3
     4 enum FwdEnum : int;
     5
     6 int main() {
     7   AddConst<FwdEnum> *ptr = nullptr;
     8 }

At line 7, when we build the type for AddConst<FwdEnum> in
lookup_template_class_1, the resulting type is the enum FwdEnum.  This
confuses lookup_template_class_1 near the if below, wrongly making it
taking the branch and thus calling tsubst_enum while it shouldn't:

      if (TREE_CODE (t) == ENUMERAL_TYPE && !is_dependent_type)
/* Now that the type has been registered on the instantiations
   list, we set up the enumerators.  Because the enumeration
   constants may involve the enumeration type itself, we make
   sure to register the type first, and then create the
   constants.  That way, doing tsubst_expr for the enumeration
   constants won't result in recursive calls here; we'll find
   the instantiation and exit above.  */
tsubst_enum (template_type, t, arglist);

Before the alias template feature, the only reason why TREE_CODE (t)
== ENUMERAL_TYPE would be true is when lookup_template_class_1 is
called for an enum that is a member of a class template.  But that
condition can be also true for an alias template instantiation.

So I guess that condition should be changed to TREE_CODE
(template_type) == ENUMERAL_TYPE, to specifically detect the member
enum of a class template case.  Note that for the alias template
instantiation case above, template_type points to a TEMPLATE_TYPE_PARM
which name is AddConst.

This is what the patchlet below does.

Bootstrapped and tested on x86_64-unknown-linux-gnu against trunk.

PR c++/54466 - ICE with alias template which type-id is const qualified

Consider this short example:

    template<typename T>
      struct X { };

    template<typename T>
      using Y = const X<T>;

    using Z = Y<int>;

G++ crashes in lookup_class_template_1 while trying to build the alias
template instantiation Y<int>.

I think this is indirectly due to the fact that that
lookup_class_template_1 can now yield a const qualified type like
'const X<T>'.

As a consequence, the code in lookup_template_class_1 that was trying
to access the TYPE_STUB_DECL field of the result of
lookup_template_class_1 should now be adjusted to access the
TYPE_STUB_DECL of the main variant of the resulting type instead (and
that is TYPE_MAIN_DECL); because qualified types (constructed with
build_qualified_type) have their TYPE_STUB_DECL set to NULL.

Fixed thus and tested on x86_64-unknown-linux-gnu against trunk.
