[LoongArch] Fold shifted vector extract comparisons

Fold comparisons of the form:

  (shl (extract_vector_elt X, I), GRLen - EleBits) ==/!= 0

into:

  (extract_vector_elt X, I) ==/!= 0

When the shift amount equals `GRLen - EleBits`, the left shift only moves
the extracted element into the most significant bits without affecting
whether the value is zero. This canonicalization exposes
EXTRACT_VECTOR_ELT to later combines and enables selecting
VPICKVE2GR_* instructions directly.
