[InstSimplify] Properly constrain {insert,extract}_subvector intrinsic fold
The previous rule:
(insert_vector _, (extract_vector X, 0), 0) -> X
is not quite correct. The correct fold should be:
(insert_vector Y, (extract_vector X, 0), 0) -> X
where: Y is X, or Y is undef
This commit updates the pattern.
