      [libc++] Make sure std::allocator<void> is always trivial
  
      When we removed the allocator<void> specialization, the triviality of
      std::allocator<void> changed because the primary template had a
      non-trivial default constructor and the specialization didn't
      (so std::allocator<void> went from trivial to non-trivial).
  
      This commit fixes that oversight by giving a trivial constructor to
      the primary template when instantiated on cv-void.
  
      This was reported in https://llvm.org/PR50299.
  
      (cherry picked from commit 71e4d434dc83b02a853712a5cb026ee2fa9ba67f)
