svn commit: r288130 - projects/clang370-import/contrib/libc++/src/support

[Dimitry Andric]

Author: dim
Date: Tue Sep 22 20:48:12 2015
New Revision: 288130
URL: https://svnweb.freebsd.org/changeset/base/288130

Log:
  Partially revert r288121, removing the workaround for arm < v6.  Since
  r288125, the required atomic library calls are available in compiler-rt.
  
  The added stub for __libcpp_relaxed_store() can stay as a fallback; I
  have also committed it upstream.
