[RISCV] Use bseti 31 for (or X, -2147483648) when upper 32 bits aren't used. (#159678)
If the original type was i32, type legalization will sign extend
the constant. This prevents it from having a single bit set or clear
so other patterns can't match. If the upper bits aren't used, we
can ignore the sign extension.
Similar for bclri and binvi.
