ld1 inserts an alignment requirement

[awxkee]

Current implementations of ld1 { vN.d }[N] insert an alignment requirement in debug builds, since a pointer dereference assumes the element is aligned to its type's size, whereas to the best of my knowledge, ld1 doesn't have any particular alignment requirements.

pub unsafe fn vld1q_lane_u32<const LANE: i32>(ptr: *const u32, src: uint32x4_t) -> uint32x4_t {
    static_assert_uimm_bits!(LANE, 2);
    simd_insert!(src, LANE as u32, *ptr)
}

pub unsafe fn vld1q_lane_u64<const LANE: i32>(ptr: *const u64, src: uint64x2_t) -> uint64x2_t {
    static_assert_uimm_bits!(LANE, 1);
    simd_insert!(src, LANE as u32, *ptr)
}
