Add CPU detection code for Ampere-1 and Ampere-1A CPUs, and configure default AArch64 options.
processor : 0
BogoMIPS :
Features :
CPU implementer : 0xc0
CPU architecture: 8
CPU variant : 0x0
CPU part : 0xac3
CPU revision : 0
By the way, GCC has already had the changes to support Ampere-1 and Ampere-1A, https://gcc.gnu.org/pipermail/gcc-patches/2022-November/605942.html. So it is time to have similar detection and support in JDK as well.
Plan to backport to 17 once the MR gets approved to mainline.
