Summary:
Makes compute call async from willReceiveProps and fixes crashes with proper bounds in render
function instead. This means that fast prop updates won't force rapid and synchronous row increments during
initial render.
Check `rowData` and `rowKey` explicitly so clients don't have to worry about preserving === rowData containers
around Relay data to prevent re-renders.
Also moves layout jump warning behind DEBUG since it's not a common issue any more.
