[RISCV] Add simple DAG combine to pull xor with 1 through select_cc.
If we're selecting the result of two setccs that have been legalized
by introducing an xor with 1, we can pull the xor with 1 through the
select to enable more optimizations.
We could generalize this to other binary operators with identical
conditions, but those are usually caught before we legalize the select.
