benchtests: Switch string benchmarks to use bench-timing.h.

Browse Source 
Switch the string benchmarks to using bench-timing.h instead
of hp-timing.h directly. This allows the string benchmarks to
be run usefully on architectures such as ARM that do not have
support for hp-timing.h.

In order to do this the tests have been changed from timing each
individual call and picking the lowest execution time recorded to
timing a number of calls and taking the mean execution time.

ChangeLog:

2013-09-04   Will Newton  <will.newton@linaro.org>

	* benchtests/bench-timing.h (TIMING_PRINT_MEAN): New macro.
	* benchtests/bench-string.h: Include bench-timing.h instead
	of including hp-timing.h directly. (INNER_LOOP_ITERS): New
	define. (HP_TIMING_BEST): Delete macro. (test_init): Remove
	call to HP_TIMING_DIFF_INIT.
	* benchtests/bench-memccpy.c: Use bench-timing.h macros
	instead of hp-timing.h macros.
	* benchtests/bench-memchr.c: Likewise.
