Auto merge of #48575 - ishitatsuyuki:unix-no-thread, r=alexcrichton
rustc_driver: get rid of the extra thread **Do not rollup** We can alter the stack size afterwards on Unix. Having a separate thread causes poor debugging experience when interrupting with signals. I have to get the backtrace of the all thread, as the main thread is waiting to join doing nothing else. This patch allows me to just run `bt` to get the desired backtrace.
