Martin Storsjö	ee040a7fc2	arm/aarch64: Use mach_absolute_time as timer on apple platforms This is much less precise than the cycle counter register, but the cycle counter register is not available on apple platforms (and on linux, it requires a kernel module for allowing user mode access).

arm/aarch64: Use mach_absolute_time as timer on apple platforms

This is much less precise than the cycle counter register, but
the cycle counter register is not available on apple platforms
(and on linux, it requires a kernel module for allowing user mode
access).

arm64: add cycle counter support

The ISB (instruction synchronization barrier) might be too heavy for
START/STOPTIMER use but should be more accurate in checkasm where the
timing overhead is subtracted.
