This test
On macOS, this test can instead return `status = 0 (0x00000000) Terminated due to signal 6`. This updates the `CHECK` accordingly.

The test only checks the exit code that the debug server sends back, but
not the following explanation which is different for debugserver and lldb-server.
If our process terminates due to an unhandled signal, we are supposed to get the
signal code via WTERMSIG. However, we instead try to get the exit status via
WEXITSTATUS which just ends up always calculating signal code 0 (at least on the
macOS implementation where it just shifts the signal code bits away and we're
left with only 0 bits).
The exit status calculation on the LLDB side also seems a bit off as it claims
an exit status that is just the signal code (instead of for example 128 + signal
code), but that will be another patch.
