Record evaluated-ness information correctly for strict constructors
The add_evals code in Simplify.simplAlt had bit-rotted. Example:
data T a = T !a
data U a = U !a
foo :: T a -> U a
foo (T x) = U x
Here we should not evaluate x before building the U result, because
the x argument of T is already evaluated.
Thanks to Roman for finding this.
