Fix candidate for PR c++/43206

gcc/cp/ChangeLog:
        PR c++/43206
        * cp-tree.h (get_template_parms_at_level): Declare ...
        * pt.c (get_template_parms_at_level): ... new function.
        * typeck.c (get_template_parms_of_dependent_type): If a template
        type parm's DECL_CONTEXT isn't yet set, get its siblings from
        current_template_parms. Use get_template_parms_at_level. Remove
        useless test.
        (incompatible_dependent_types_p): If we get empty parms from just one
        of the template type parms we are comparing then the template parms are
        incompatible.

gcc/testsuite/ChangeLog:
        PR c++/43206
