I don't see how such small slowdowns could be serious enough for us to
bother.  We are not even sure the two binaries were built by the same
version of GCC, are we?

So I'm closing this bug; if someone wants to investigate the sources
of this slowdown, or finds a case where the difference is much larger,
we can always reopen.
