[aarch64-port-dev ] RFR(T): 8226222: [JVMCI] Export AArch64 field VM_Version::_psr_info.dczid_el0

[Pengfei Li (Arm Technology China)]

Hi,

Could you help review this small change on JVMCI?

Webrev: http://cr.openjdk.java.net/~pli/rfr/8226222/webrev.00/
JBS: https://bugs.openjdk.java.net/browse/JDK-8226222

We would like to implement memory bulk zeroing by cache maintenance (DC ZVA) instruction in AArch64 Graal compiler. To make AArch64 processor info "dczid_el0" available to get at compile-time, this patch exports AArch64 HotSpot field VM_Version::_psr_info.dczid_el0 and also fixes out-of-date AArch64 macro in JVMCI.
