[ARM] Be super conservative about atomics

As requested during review of D57601 https://reviews.llvm.org/D57601 https://reviews.llvm.org/D57601, be equally conservative for atomic MMOs as for volatile MMOs in all in tree backends. At the moment, all atomic MMOs are also volatile, but I'm about to change that.

Differential Revision: https://reviews.llvm.org/D58490

Note: D58498 landed in several pieces as individual backends were approved. This is the last chunk.
llvm-svn: 354845
