I'm working on some IRA cost fixes, and I've had the lzcnt-1.c test fail
because the register allocator started making different decisions. In
both cases we end up generating two instructions, but with slightly
different register assignments. Hence, this patch, which relaxes the
test slightly.

Bootstrapped and tested on x86_64-linux (with my IRA changes, so I
probably ought to try without those as well). Ok?

OK.
