Fix PR4313: IPSCCP was not setting the lattice value for the invoke instruction
...
when the invoke had multiple return values: it set the lattice value only on the
extractvalue.
This caused the invoke's lattice value to remain the default (undefined), and
later propagated to extractvalue's operand, which incorrectly introduces
undefined behavior.

- Some clients which used DOUT have moved to DEBUG. We are deprecating the

downside of leaving code in -Asserts builds, and of hiding potentially
