All the cool kids say this is the best thing since sliced bread.

For the most part, these changes match what glibc does.

4d8fe5177e Tune the memcpy for krait. 
Streamline the memcpy a bit removing some unnecessary instructions.

The biggest speed improvement comes from changing the size of
the preload. On krait, the sweet spot for the preload in the main
loop is twice the L1 cache line size.

In most cases, these small tweaks yield > 1000MB/s speed ups. As
the size of the memcpy approaches about 1MB, the speed improvement
disappears.

1aae9bd170 strncpy: implement _FORTIFY_SOURCE=2 
Add support for fortify source level 2 to strncpy.
This will enable detection of more areas where strncpy
is used inappropriately. For example, this would have detected
bug 8727221.

Move the fortify_source tests out of string_test.cpp, and
put it into fortify1_test.cpp.

Create a new fortify2_test.cpp file, which copies all
the tests in fortify1_test.cpp, and adds fortify_source level
2 specific tests.
