clocks - Add fine-grained spin delay function via TSC
Add int64_t target = tsc_get_target(ns) and tsc_test_target(target).
See routines for details. These functions are available when the system
supports an extremely fine-grained counter such as a TSC and may be used
to generate finely tuned delays.
