all_true requires the input to be of the respective type, but the
final result is always a Int32x4 with a single node. So keep
the replacement type of all_true (and any_true) nodes to be Int32x4,
and use a helper method to decide what SimdType the input should
be replaced with.

Also split up any_true and all_true for readability.
