  -----------
  [LoongArch] Add atomic ordering information for binary atomic operations

This patch also implements not emit fence in atomic binary operation
when AtomicOrdering is monotonic and fixes the issue of loading from
non ptr parameters.

The processing of other levels of AtomicOrdering will be added later.
