Add ssse3 implementation of __memcmp16.

__memcmp16 was missing in x86. Also added C-version for backward
compatibility. Added bionic test for __memcmp16 and for wmemcmp.

fix broken pointer overflow check ns_name_unpack()

Many compilers optimize away the overflow check `msg + l < msg',
where `msg' is a pointer and `l' is an integer, because pointer
overflow is undefined behavior in C.

Use a safe precondition test `l >= eol - msg' instead.

Change hard-coded temporary directory.

The properties tests creates a temporary directory in /data/nativetest,
but this directory might not exist in all circumstances.
Change this to create the temporary directory in /data/local/tmp.

Add bionic-unit-tests-run-on-host special target

Allows running the tests linked with bionic .so on the host if host and
target are compatible. See more comments and usage limitation inlined.

make bionic-unit-tests-run-on-host should do build and run.

Make cpp.py less braindead.

The old code ignored operator precedence (!), despite having two tables
of operator precedence. The code's still pretty awful, but I've cleaned
it up enough to fix this, the most important bug.

This patch lets us correctly clean the uapi unistd.h, stat.h, and swab.h files,
and also fixes the mess we were already making of various old kernel
header files. I've added a bunch more tests, fixed the existing tests that
the existing script was already failing (!), and changed the script so that
the tests are run every time the script is run.

We can probably remove some of the old kernel header files that we were
parsing incorrectly, but we can worry about that later.

Remove the dependency on the non-uapi __kernel_nlink_t.

The kernel doesn't have an nlink_t; it just uses the equivalent of
uint32_t. We already had a usable __nlink_t in the C library, so
let's just define our nlink_t in terms of __nlink_t, which is what
__nlink_t was meant for anyway.

Note that our struct stat just follows the kernel, and doesn't refer
to nlink_t anyway.
