[PATCH] RISC-V: Remove the redundant expressions in the and3.

When generating the gen_and3 function based on the and3 template, it produces the expression emit_insn (gen_rtx_SET (operand0, gen_rtx_AND (, operand1, operand2)));, which is identical to the portion I removed in this patch. Therefore, the redundant portion can be deleted. Signed-off-by: Die Li
