- Instead of lowering float/double ISD::ATOMIC_LOAD / ISD::ATOMIC_STORE nodes to regular LOAD/STORE nodes, make them legal and select those nodes properly instead. This avoids exposing them to the DAGCombiner. - AtomicExpand pass no longer casts float/double atomic load/stores to integer (FP128 is still casted).
