Jonas Paulsson 8ae0f88b13 [SystemZ::TTI] Return zero cost for ICmp that becomes Load And Test. ... A loaded value with multiple users compared with 0 will become a load and test single instruction. The load is not folded in this case (multiple users), but the compare instruction is eliminated. This patch returns 0 cost for the icmp in these cases.
