RFR: 8285040: PPC64 intrinsics for divideUnsigned and remainderUnsigned methods in java.lang.Integer and java.lang.Long [v2]

Wed Apr 20 10:15:08 UTC 2022

> Add match rules for UDivI, UModI, UDivL, UModL as on x86 (JDK-8282221). PPC64 doesn't have DivMod instructions which can deliver both results at once.
> Note: The x86 tests can currently not be extended to this platform because https://bugs.openjdk.java.net/browse/JDK-8280120 is not yet implemented.

Martin Doerr has updated the pull request incrementally with one additional commit since the last revision:

  Remove UDivI and UModI again because they don't improve performance.
