re PR target/88234 (UBsan and runtime error: signed integer overflow using unsigned vector)
PR target/88234
* config/rs6000/rs6000.c (rs6000_gimple_fold_builtin): For
vec_add and vec_sub builtins, perform PLUS_EXPR or MINUS_EXPR
in unsigned_type_for instead of vector integral type where overflow
doesn't wrap.
* gcc.dg/ubsan/pr88234.c: New test.
