[compiler] Remove AtomicNarrow machine operators, macroize tests 

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
