Yuval Pavel Zholkover 744ccbb852 runtime: fast clock_gettime call on FreeBSD 
Use AT_TIMEKEEP ELF aux entry to access a kernel mapped ring of timehands structs.
The timehands are updated by the kernel periodically, but for accurate measure the
timecounter still needs to be queried.
Currently the fast path is used only when kern.timecounter.hardware==TSC-low
or kern.timecounter.hardware=='ARM MPCore Timecounter',
other timecounters revert back to regular system call.

TODO: add support for HPET timecounter on 386/amd64.
