<pre>Example:
template <auto> struct foo { static constexpr int value = 0; };
template <int I> struct foo<I> { static constexpr int value = 1; };
static_assert(foo<42L>::value == 0);
According to clang, foo<42L>::value is 1, but the partial specialization should
not match here (we fail [temp.deduct.type]/19 because the type of 42L differs
from the type of the parameter).</pre>
