[Kernel] Build an invalid constant for evaluation errors

An invalid constant is (currently) represented by an unevaluated
invalid expression.  Using this instead of null fixes 63 out of 125
CFE constant-evaluation crashes with constant-update-2018 and
correctly signals 26 more previously-missed compile-time errors.
