  Hi.

single-step.exp takes a while to run, and while that's not necessarily
bad, here it's because the default value of SINGLE_STEP_COUNT is 10,000.

We're not going to gain any more insight into perf issues
single-stepping (stepi) 10,000 times over 1,000 times,
so this patch changes the default to 1,000.

IWBN to rename "single-step" to something like "single-stepi"
or some such as the name is misleading, but that's left for
another patch.
