ARM: Use "dmb sy" for barriers on M-class CPUs The usual default of "dmb ish" (inner-shareable) isn't even a valid instruction on v6M or v7M (well, it does the same thing but software is strongly discouraged from using it) so we should emit a full-system barrier there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189483 91177308-0d34-0410-b5e6-96231b3b80d8
