MFC r230393:

Pull in r148240 from upstream llvm trunk:

  Make sure the non-SSE lowering for fences correctly clobbers EFLAGS.
  PR11768.

In particular, this fixes segfaults during the build of devel/icu on
i386.  The __sync_synchronize() builtin used for implementing icu's
internal barrier could lead to incorrect behaviour.
