RFR(S): 8164102: MethodHandles.countedLoop/4 works incorrect for start/end = Integer.MAX_VALUE

[Michael Haupt]

Dear all,

please review this fix.
Bug: https://bugs.openjdk.java.net/browse/JDK-8164102
Webrev: http://cr.openjdk.java.net/~mhaupt/8164102/webrev.00/

The countedLoop implementation would yield loops with wrong iteration counts if start and end values around the fringes of the int value space were chosen. The fix - passing the decremented counter value to the predicate as well as the body - is temporary, as a larger overhaul of the JEP 274 API is under way as part of the fix to JDK-8151179.

Thanks,

Michael
