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.
