Leszek Swirski authored
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, leading to a crash.

- Fix tracing of reference return values. StoreTaggedPointer should not use the write barrier since we are writing to the stack. - Avoid re-allocating a slot for the return value when it is already spilled.

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.
