[RISCV] Do not outline CFI instructions when they are needed in EH

We saw a failure caused by unwinding with incomplete CFIs, so we
can't outline CFI instructions when they are needed in EH.

This is a recommit of 0d40688, which was reverted in ce83883 as
related precommit test 360d44e caused some errors.
