Thanks for your review @PaulSandoz ! Yes, reusing `VectorSupport.compare` is an
alternative way to do the vectorization.

Currently `"VectorMask.eq()" `is not vectorized:
public VectorMask eq(VectorMask m) {
// FIXME: Generate good code here.
return bOp(m, (i, a, b) -> a == b);
}
This can be implemented by calling `"xor(m.not())"` directly.
The performance improved about 1.4x ~ 1.9x for the
