c++: tighten TMPL_ARGS_LEVEL macro
This patch makes TMPL_ARGS_LEVEL verify the level argument is valid when
the one-dimensional vector case. Doing so uncovered a couple of latent
issues: in try_class_unification, we weren't correctly copying targs
when it's two-dimensional, and in unify_pack_expansion it seems an
inequality test needs to be reversed. This patch fixes both issues, and
in passing makes the former function free the temporary copy of targs.
gcc/cp/ChangeLog:
* cp-tree.h (TMPL_ARGS_LEVEL): Assert LEVEL is 1 when
TMPL_ARGS_HAVE_MULTIPLE_LEVELS is false.
* pt.cc (try_class_unification): Correctly copy multidimensional
targs. Free the copy of targs.
(unify_pack_expansion): Fix level comparison.
