PR c++/54401 - Confusing diagnostics about type-alias at class scope

Consider this invalid example given in the PR, where T is not defined:

     1 template<typename>
     2 struct X {
     3     using type = T;
     4 };

g++ yields the confusing diagnostics:

test.cc:3:10: error: expected nested-name-specifier before 'type'
    using type = T;
          ^
test.cc:3:10: error: using-declaration for non-member at class scope
test.cc:3:15: error: expected ';' before '=' token
    using type = T;
               ^
test.cc:3:15: error: expected unqualified-id before '=' token

I think this is because in cp_parser_member_declaration we tentatively
parse an alias declaration; we then have a somewhat meaningful
diagnostic which alas is not emitted because we are parsing
tentatively.  As the parsing didn't succeed (because the input is
invalid) we try to parse a using declaration, which fails as well; but
then the diagnostic emitted is the one for the failed attempt at
parsing a using declaration, not an alias declaration.  Oops.

The idea of this patch is to commit the tentative parse when we see
the '=' token in the alias-declaration.  That way any error encounter
after that token is reported to the user.

We are now getting the following output:

    test.cc:3:18: erreur: expected type-specifier before ‘T’
 using type = T;
      ^
    test.cc:3:18: erreur: ‘T’ does not name a type

I don't really like the "before 'T'" there, but I think we maybe could
revisit the format of what cp_parser_error emits in general, now that
we have caret diagnostics;  We could maybe do away with the "before T"
altogether?

In the mean time, it seems to me that this patch brings an improvement
over what we already have in trunk, and the issue above could be
addressed separately.
