Exception handlers were allowing register state to leak through, which
had knock-on effects of Phi allocation inserting gap moves in an illegal
location (specifically, at the end of the block, thinking that it's
allocating a control node since it's not allocating a body node).
Fix the register leak by clearing register state, and add some invariant
guards in the areas where the failure appeared.

When externalizing a string, the external pointer slots need to be
initialized before the new Map is installed. Otherwise, a GC marking
thread may see the new Map before the slots are valid. In that case, it
would attempt to mark invalid ExternalPointerTable entries as alive,

On termination of the worker pool in the main process, a SIGTERM is
sent from pool to worker. It was meant to terminate long-running
tests in the worker process. The signal handler on the worker side,
however, was only registered during test execution. During the
remaining logic (<1% of the time probably) the default system
behavior for SIGTERM would be used (which will likely just kill
the process). The ungracefully killed process might be killed while
writing to the results queue, which then remains with corrupted data.
Later when the main process cleans up the queue, it hangs.
We now register a default handler in the worker process that catches
the SIGTERM and also gracefully stops the processing loop. Like
that, the SIGTERM signal will always be handled in workers and never
fall back to SIGKILL.
However, a small time window exists when the SIGTERM was caught
right when starting a test process, but when the test-abort handler
was not registered yet. We keep fixing this as a TODO. Worst case,
the main process will block until the last test run is done.
