Eli Friedman 0389f2edf7 Revert "[compiler-rt] Implement ARM atomic operations for architectures without SMP support"
This reverts commit 910a642c0a5b66a8d2517026b890a1acdc447f19.

There are serious correctness issues with the current approach: __sync_*
routines which are not actually atomic should not be enabled by default.

I'll continue discussion on the review.
