Florian Hahn dafcef6848 [IPSCCP] Add getCompare which returns either true, false, undef or null. ...

getCompare returns true, false or undef constants if the comparison can
be evaluated, or nullptr if it cannot. This is in line with what
ConstantExpr::getCompare returns. It also allows us to use
ConstantExpr::getCompare for comparing constants.
