Primitive template arguments not evaluated when matching partial specialisation

[davmac314]

Describe the bug
Non-literal primitive template arguments not evaluated when matching partial specialisation.

To Reproduce

template <typename T> constexpr bool consume_r1() { return true; }
template <class T1, bool EN = true> class A { };
template <class T1> class A <T1, (bool)consume_r1<T1>() > {
    constexpr static int val = 99;
};

A<int> a1; // should use specialisation

int f = a1.val; // error marked (incorrect!)

Expected behavior
The line marked with an error should not be marked, it has no error. The issue is that CDT does not use the partial specialisation of A which defines the val member, though it should.
