Refactor hp-timing rtld usage
This patch refactor how hp-timing is used on loader code for statistics report. The HP_TIMING_AVAIL and HP_SMALL_TIMING_AVAIL are removed and HP_TIMING_INLINE is used instead to check for hp-timing avaliability. For alpha, which only defines HP_SMALL_TIMING_AVAIL, the HP_TIMING_INLINE is set iff for IS_IN(rtld). Checked on aarch64-linux-gnu, x86_64-linux-gnu, and i686-linux-gnu. I also checked the builds for all afected ABIs. * benchtests/bench-timing.h: Replace HP_TIMING_AVAIL with HP_TIMING_INLINE. * nptl/descr.h: Likewise. * elf/rtld.c (RLTD_TIMING_DECLARE, RTLD_TIMING_NOW, RTLD_TIMING_DIFF, RTLD_TIMING_ACCUM_NT, RTLD_TIMING_SET): Define. (dl_start_final_info, _dl_start_final, dl_main, print_statistics): Abstract hp-timing usage with RTLD_* macros. * sysdeps/alpha/hp-timing.h (HP_TIMING_INLINE): Define iff IS_IN(rtld). (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Remove. * sysdeps/generic/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL, HP_TIMING_NONAVAIL): Likewise. * sysdeps/ia64/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Likewise. * sysdeps/powerpc/powerpc32/power4/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Likewise. * sysdeps/powerpc/powerpc64/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Likewise. * sysdeps/sparc/sparc32/sparcv9/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Likewise. * sysdeps/sparc/sparc64/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Likewise. * sysdeps/x86/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Likewise. * sysdeps/generic/hp-timing-common.h: Update comment with HP_TIMING_AVAIL removal.
