CL 33239 changed the polling loops from using sched_yield to a sleep
for 1/1000 of a second. The loop counters were not updated, so failing
tests now take 100 seconds to complete. Lower the loop counts to 5
seconds instead.

Apparently when GOMAXPROCS == 1 a simple sched_yield in a tight loop is
not necessarily sufficient to permit a signal handler to run. Instead,
sleep for 1/1000 of a second.
Fixes#16649.

The old code assumed that the thread ID set by pthread_create would be
available in the newly created thread. While that is clearly true
eventually, it is not necessarily true immediately. Rather than try to
pass down the thread ID, just call pthread_self in the created thread.
Fixes#15576 (I hope).

After a failure on the build dashboard I tested testcarchive test 2 and
found that it failed an average of 1 in 475 runs on my laptop. With
this change it ran over 50,000 times without failing. I bumped up the
other iteration limits to correspond.

When calling a Go function on a C thread, if the C thread already has an
alternate signal stack, use that signal stack instead of installing a
new one.
