  D3D: fix whole-array assignment to SSBOs.
  
  SSBOs in HLSL are implemented as RWByteAddressBuffer, which can only
  Load() or Store() up to 16 bytes at a time, so value-assignment of
  arrays doesn't work. The fix is to implement a traversal which
  unfolds such assignments into an element-by-element for-loop.
