Craig Topper 8ed046fc15 [RISCV] Custom type legalize i32 SADDSAT/SSUBSAT without Zbb. ...

While working on -riscv-experimental-rv64-legal-i32, I noticed this
missed optimization in our current codegen.

This expands to SADDO/SSUBO+select while still in i32. These will
be type legalized individually.
