Add generic hp-timing support
Add missing generic hp_timing support.  It uses clock_gettime (CLOCK_MONOTONIC)
which has unspecified starting time, nano-second accuracy, and should faster on
architectures that implementes the symbol as vDSO.

Checked on aarch64-linux-gnu, x86_64-linux-gnu, and i686-linux-gnu. I also
checked the builds for all afected ABIs.

	* benchtests/Makefile (USE_CLOCK_GETTIME) Remove.
	* benchtests/README: Update description.
	* benchtests/bench-timing.h: Default to hp-timing.
	* sysdeps/generic/hp-timing.h (HP_TIMING_DIFF, HP_TIMING_ACCUM_NT,
	HP_TIMING_PRINT): Remove.
	(HP_TIMING_NOW): Add generic implementation.
	(hp_timing_t): Change to uint64_t.
