Simon Dardis 92365cae1c Reland "[mips][compiler-rt] Provide 64bit atomic add and sub" 
r318733 introduced a build failure for native MIPS32 systems for xray due
to the lack of __sync_fetch_and_add / __syn_fetch_and_sub support. This patch
extends the existing support providing atomics so that xray can be
successfully built.

The initial patch was reverted in r321292, as I suspected it may have caused the
buildbot failure. Another patch in the updates the bot fetched caused the test
failures which was reverted.

Simon Dardis 6e62834fef Revert "[mips][compiler-rt] Provide 64bit atomic add and sub" 
This reverts commit r321260. It appears to have broken the sanitizer
bot sanitizer-ppc64be-linux.

http://lab.llvm.org:8011/builders/sanitizer-ppc64be-linux/builds/5029

Reverting to see if the buildbot turns green.
