  Revert "[RISCV] Use zexti32/sexti32 in srliw/sraiw isel patterns to improve usage of those instructions."

I thought this might help with another optimization I was
thinking about, but I don't think it will. So it just wastes
compile time calling computeKnownBits for no benefit.

This reverts commit 81b2f95971edd47a0057ac4a77b674d7ea620c01.
