qfloat16 explicitly implements all relational operators for comparing with various FP types (float, double, long double), but for integral types it provides only operators for comparison with int.

As a result, code like that will fail to compile:

qfloat16 f16 = 1.0;
int i = 1;
qint64 i64 = 1;

qDebug() << (f16 == i); // fine, we have explicit operator==(qfloat16, int)
qDebug() << (f16 == i64); // ERROR: ambiguity

This is discovered while working on C++20 comparison story, but this is a pre-existing problem.

So, should we provide comparison operator overloads for all integral types (signed and unsigned)?
