  -----------
  [StatepointLowering] Take return attributes of `gc.result` into account (#68439)

The current lowering of statepoints does not take into account return
attributes present on the `gc.result` leading to different code being
generated than if one were to not use statepoints. These return
attributes can affect the ABI which is why it is important that they are
applied in the lowering.
