EHTerminateScope is used to implement C++ noexcept semantics, and per
C++ [except.terminate], it is implemented-defined whether no, some, or
all cleanups are run prior to terminate.

We now define the behavior as "some" -- cleanups in nested function
calls will still be run, but not those in the noexcept function
itself.
