This is the new replacement for the existing cortex-strings code which will be replaced in a follow-up commit. We should also be able to use some of the math functions to allow the tests to pass on AArch64 (and other architectures) instead of just x86. We might also be able to reuse some of the tests for the kyua testsuite. Imported using ``` curl -Le823e3abf5| tar --strip-components=1 -xvzf - git add . ``` Differential Revision: https://reviews.freebsd.org/D29035 git-subtree-dir: contrib/arm-optimized-routines git-subtree-mainline:e34c713b0egit-subtree-split:f9f37c002a
