New version. On aarch64 the jdk wants hardware capablities and cpu
info so it can adjust its behavior to conform to the hardware ablities.
This diff uses elf_aux_info(3) for hardware capablities and if
HWCAP_CPUID is set will use READ_SPECIALREG(midr_el1) to obtain
the cpu info. If HWCAP_CPUID is not set it will fallback to parsing
sysctl hw.model output to lookup the cpu info.
This has been tested on Apple Mac Mini (M2 Pro, 2023) which supports
HWCAP_CPUID and Pine64 RockPro64 v2.1 which does not support
HWCAP_CPUID. It also corrects some deadlocks I was seeing on the
Mac Mini in the tier1 tests.
okay?
