gprofng: Add hardware counter profiling for the Ampere system
gprofng should recognize Ampere and other ARM systems.
gprofng/ChangeLog
2024-02-22 Vladimir Mezentsev <vladimir.mezentsev@oracle.com>
* common/hwc_cpus.h: Declare the enum values ARM_CPU_IMP_*.
* common/core_pcbe.c (core_pcbe_init): Accept new systems ARM_CPU_IMP_*.
