Ross McIlroy 0403beb4bb Reland "[TurboProp] Avoid marking the output of a call live in its catch handler"
This is a reland of cdc8d9a5ec

Skipped tests on gc_stress and fixed CONSTEXPR_DCHECK for gcc.

Original change's description:
> [TurboProp] Avoid marking the output of a call live in its catch handler
>
> The output of a call won't be live if an exception is thrown while the
> call is on the stack and we unwind to a catch handler.
