Scott McMurray 511bf307f0 Emit trunc nuw for unchecked shifts and to_immediate_scalar
- For shifts this shrinks the IR by no longer needing an `assume` while still providing the UB information
- Having this on the `i8`→`i1` truncations will hopefully help with some places that have to load `i8`s or pass those in LLVM structs without range information
