Rafael Espindola 7fef5a3d19 SimplifyCFG: Avoid miscompilations due to removed lifetime intrinsics. ...

The lifetime intrinsics need some work in order to make it clear which
optimizations are or are not valid.

For now dropping this optimization avoids a miscompilation.

Patch by Björn Steinbrink.
