KnownValue(HasKnownValue &&
----------------
Oof, this adds quite a bit of expense to this constructor --
`isIntegerConstantExpr()` is implemented by evaluating the constant expression
and throwing away the computed result... which we then recompute when setting
`KnownValue` one line later. It'd be better to only do this computation once
and use the computed value to initialize both members.
