[BUG] poly64 load intrinsics are not available on v7

[Jmc18134]

The intrinsics vld1_p64 and vld1q_p64, as well as other intrinsics that construct poly64s like vcreate_p64 and vreinterpret_p64_s32 are not supported for v7, even though intrinsics accepting poly64 vectors as arguments like vadd_p64 are supported (with no way to construct their arguments).
