[RISCV] Add isel pattern for (mul (and X, 0xffffffff), 3<<C) with Zba.
We can use slli.uw by C followed by sh1add. Similar can be done
for multiples of 5 and 9. We need to make sure that C is less than
32 to stay in bounds of the 5-bit immediate for slli.uw.
We have existing patterns for (mul X, 3<<C) that use sh1add
followed by slli. That order doesn't allow the and to be folded.
