PR middle-end/53676
* tree-chrec.c (chrec_convert_1): Represent truncation to
a type with undefined overflow as truncation to an unsigned
type converted to the type with undefined overflow.
* tree-scalar-evolution.c (interpret_rhs_expr): For computing
the scalar evolution of a truncated widened operation avoid
looking at the non-existing evolution of the widened operation
result.
* gcc.dg/tree-ssa/scev-6.c: New testcase.
