  D3D: Asynchronously load program binaries.
  
  Unpack as much of the binary steam as possible before passing the final loading
  of the shader programs off to a worker thread.  Reporting as many possible link
  errors before becoming asynchronous means that linking should only fail due to
  unexpected system issues at that point.
  
  This also allows other backends to asynchronously load program binaries.
