Mark Johnston 920de6a15f Add LSE-based atomic(9) implementations.
These make use of the cas*, ld* and swp instructions added in ARMv8.1.
Testing shows them to be significantly more performant than LL/SC-based
implementations.

No functional change here since the wrappers still unconditionally
select the _llsc variants.
