Log:
  Merge commit 371ea70bb from llvm git (by Louis Dionne):
  
    [libc++] Harden usage of static_assert against C++03
  
    In C++03, we emulate static_assert with a macro, and we must
    parenthesize multiple arguments.
  
    llvm-svn: 373328
  
  This is a follow-up to r354460, which causes errors for pre-C++11
  programs using <cmath>, similar to:
  
  /usr/include/c++/v1/cmath:622:68: error: too many arguments provided to
  function-like macro invocation
  
  Reported by:	antoine
  MFC after:	immediately (because of ports breakage)
