Please review this backport request for JDK-8206895<https://bugs.openjdk.java.net/browse/JDK-8206895>: aarch64: rework error-prone cmp instruction.
Original review thread: https://mail.openjdk.java.net/pipermail/hotspot-dev/2018-July/033461.html
This backport required fixes to three hunks and the omission of one hunk entirely.
macroAssembler_aarch64.cpp required hunk 19 to be manually applied, and stubGenerator_aarch64.cpp required hunk 7 and 13 to be manually applied.
I have omitted hunk 15 from the backport as JDK-8218966<https://bugs.openjdk.java.net/browse/JDK-8218966> was backported previously, which overwrites that section with a bug fix.
The backport compiles without issue and passes all Tier1 Hotspot tests.
