  [clang] fix nondeduced mismatch with nullptr template arguments

In deduction, when comparing template arguments of value kind,
we should check if the value matches. Values of different types can
still match. For example, `short(0)` matches `int(0)`.

Values of nullptr kind always match each other, since there is only
one such possible value. Similarly to integrals, the type does not
matter.
