Record transformation does not work with multiple return types

Fails in phase -bpopt:dss

Given for example a function signature

struct Vector3[N], struct Vector3[N] foo()

One phase earlier (-bpopt:eudt) we have

enclosed(_MAIN::_struct_Vector3)[N], enclosed(_MAIN::_struct_Vector3)[N] foo()

But after dss only the first ret is transformed and the second one is removed:

double[N], double[N], double[N] foo()
