Update micro_bench.
Moving the code to cpp to access the cpuset CPU* macros (these
macros are defined in sched.h inside of __USE_GNU which is not
defined for the thumb C compiler). The C++ code is also slightly
easier to read.
Add code to set the priority of the process to the highest value.
Add code to lock the process to a single cpu.
Add the ability to compute average and standard deviation over
a number of iterations.
Change the timing code to use nanosecond resolution timing.
Add options to allow modification of the alignment of the src/dst
pointers for memcpy and the dst pointer for memset.
Add an option to change the size of the data being copied in each
iteration.

Add a static variant for micro_bench.
So that it will be easier to test target-dependent bionic implementations
across devices.

Add a couple of performance debug utilities.
micro_bench provides very simple tests for
o sleep accuracy
o cpu
o memcpy
o memset
sane_schedstat is a front-end for /proc/schedstat to diff and format the
counters.
