This includes the following: - AARCH64 perf registers definition and hooks, - compat mode registers use, i.e. profiling a 32-bit binary on a 64-bit system, - unwinding using the dwarf information from the .debug_frame section of the ELF binary, - unwinding using the frame pointer information; in 64-bit and compat modes. Note: support for unwinding using the dwarf information in compat mode requires some changes to the libunwind code. Those changes have been submitted on the libunwind ML and are in discussion. Tested on ARMv7, ARMv8 and x86_64 platforms. The compat mode has been tested on ARMv8 using statically built 32-bit binaries.
