[RISCV] Remove unnecessary vand.vi from vXi1 and nvXvi1 VECTOR_REVERSE codegen. (#109071)
Use a setne with 0 instead of a trunc. We know we zero extended the node
so we can get by with a non-zero check only. The truncate lowering
doesn't know that we zero extended so has to mask the lsb.
I don't think DAG combine sees the trunc before we lower it to RISCVISD
nodes so we don't get a chance to use computeKnownBits to remove the
AND.
