d064591266 Further improve string bench timing 
Further improve the timings of the string benchmarks.  Ensure most take
between 1 and 4 seconds to improve accuracy.  Overall time taken increases
by 35%.  Tested on AArch64.

b598e13477 Adjust benchtests to new support library. 
This patch basically replaces the test-skeleton.c inclusion by
support/test-driver.c and also minor adjustments in bench-string.h.

Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

	* benchtests/bench-string.h (TEST_FUNCTION): Use name without
	parenthesis.
	(CMDLINE_PROCESS): Define using function instead of macro.

bd939d2322 print length in strrchr benchtest 
The return criteria of strrchr() is to read till NULL even if the
search character is hit.  So its better to print len instead of pos.

44558701ff benchtests: Switch string benchmarks to use bench-timing.h. 
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.
