This test spends most of its time sleeping and waiting on a subprocess
to sleep. It seems like a prime candidate to run in parallel, although
we may need to relax its hard-coded 2s timeout on the sleep(1)
subprocess.

According to https://man7.org/linux/man-pages/man7/signal.7.html, the
default behavior of SIGIO is to terminate the program. The Go runtime
changes that behavior with its own signal handler, so the program will
terminate if we send the signal before the runtime has finished
setting up.

It appears that at least the OpenBSD kernel gets sloppier the longer
the timeout we give it, up to an observed overhead of around 25%.
Let's give it a little more than that (33%) in the comparison, and
also increase the growth curve to match the actual observed times
instead of exponential initial growth.

go work sync panics when there are no workspace modules. This is
because the code that set the pruning mode only did so with modules
present. This change changes pruningForGoVersion to properly return
workspace pruning in workspace mode to prevent that. Another weird
scenario can happen when there are no workspace modules, but the
command-line-arguments module is created by default. Check for that
when iterating over the workspace modules to avoid trying to find the
nonexistant go.mod file for that modules.

These tests were checking for fairly narrow timing windows, but were
running in parallel and heavily dependent on timer and goroutine
scheduling. This change eliminates unnecessary goroutines, runs the
tests sequentially (dramatically shortening the timeouts to reduce the
penalty of doing so), and uses timestamp comparison instead of
background timers to hopefully gain some robustness from monotonic
timestamps.
Many of the other tests from this package would benefit from similar
simplifications, which we can apply if and when we notice flaky
failures or want to improve the latency of running the test.

It causes a crash because of the unexpected XDOT operation. It's not
needed, since we will run ComputeAddrTaken() on function instantiations
after stenciling. And it's not always correct, since we may not be able
to distinguish between a array and a slice, if a type is dependent on a
type param.
However, we do need to call ComputeAddrTaken on instantiations created
during inlining, since that is after the main ComputeAddrTaken pass.
