SI-7418 Avoid concurrent use of compiler in REPL startup
Enable the tab completer *after* we're finished binding
$intp and unleashing power mode on the asynchronous
REPL startup thread.
Tested manually:
- run qbin/scala
- Paste "".toUp
- Hit <TAB> like a maniac
Before this patch, the crash was reproducible almost every time.
Afterwards, not the once.
