Newest libunwind does support ARM64, and perf is able to utilize it
also.
This patch enables the perf test dwarf unwind for arm64.
Test result:
# ./perf test unwind
25: Test dwarf unwind : Ok

perf tools: Fix arm64 build error
I'm seeing the following build error on arm64:
In file included from util/event.c:3:0:
util/event.h:95:17: error: 'PERF_REGS_MAX' undeclared here (not in a function)
u64 cache_regs[PERF_REGS_MAX];
^
This patch adds a PERF_REGS_MAX definition for arm64.
