* YJIT: Add --yjit-pause and RubyVM::YJIT.resume This allows booting YJIT in a suspended state. We chose to add a new command line option as opposed to simply allowing YJIT.resume to work without any command line option because it allows for combining with YJIT tuning command line options. It also simpifies implementation. Paired with Kokubun and Maxime. * Update yjit.rb Co-authored-by: Takashi Kokubun <takashikkbn@gmail.com> --------- Co-authored-by: Alan Wu <XrXr@users.noreply.github.com> Co-authored-by: Takashi Kokubun <takashikkbn@gmail.com>
