I thought I had said something about this.

Basically I have no objection to the optimizers removing empty loops.
The old arguments against removing them were lame to start with and
they're even more lame now.

If someone wants to submit code to allow loop.c to remove such loops,
it will not be rejected because "gcc isn't supposed to remove empty
loops".
