      [compiler] Remove AtomicNarrow machine operators, macroize tests · 9a0f2546
      Deepti Gandluri authored
      The AtomicNarrow operations are currently used for wider 64-bit
      operations, that only operate on 32-bits of data or less
      (Ex:I64AtomicAdd8U). Removing these because this can be handled
      in int64-lowering by zeroing the higher order node.
      Explicitly zeroing these in code-gen is not
      required because -
      
       - The spec requires only the data exchange to be atomic, for narrow
         ops this uses only the low word.
       - The return values are not in memory, so are not visible to other
         workers/threads
