      Description

      We would like to implement memory bulk zeroing with 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available to get at compile-time, this patch exports AArch64 HotSpot field VM_Version::_psr_info.dczid and also fixes out-of-date macro in JVMCI.
