Driver: make it easier to select the SjLj EH model
GCC still permits enabling the SjLj EH model. This is something which can be
done on various targets. Hoist the -fsjlj-exceptions option into the driver and
pass it through. This allows one to opt into the alternative EH model while
retaining the default to be the target's default.
