[PATCH, RFC] combine: Don't truncate const operand of AND if it's no benefits

Hi, This patch tries to fix the problem when a canonical form doesn't benefit on a specific target. The const operand of AND is and with the nonzero bits of another operand in combine pass. It's a canonical form, but it's no benefits for the target which has rotate and mask insns. As the mask is
