[aarch64-port-dev ] RFR(S): 8210413: AArch64: Optimize div/rem by constant in C1

[Pengfei Li (Arm Technology China)]

Hi Andrew,

Please find below new patch that added the same optimization for longs as well as ints and also fixed an issue.
http://cr.openjdk.java.net/~yzhang/8210413/webrev.01/

Could you help look at it again?

Thanks,
