D3D11: map index buffers only when needed.
Before this patch, index buffers where always mapped in case we needed the
index data for the indexed point sprites workaround.
This patch makes it so the index buffer is only mapped in this case, when
we need to stream index data or when we need to fill the static copies of
the index buffers.
This make the memory usage of
http://alteredqualia.com/xg/examples/mammoth.html go down from 41MB to
28MB.
