JDK-8234160 - Enable optimized mitigation for Intel jcc erratum in C2
Description
Since JDK-8234160, HotSpot contains a flag VMVersion::_has_intel_jcc_erratum, which can tell the CPU models affected by Intel JCC Erratum. A JVMCI compiler can also use such a flag to toggle the Intel JCC erratum mitigation automatically.
Comments
11u backport Mark as jdk11u-jvmci-defer. Given the many missing JVMCI changes I skip this one.
