Agreed.  If I can't figure out a nice way to do this soon, I'll
probably drop support for 64bit index types.  This will cut the
compile time in half and it is only necessary for matrices with >=
2^31 row or columns.  Since that would require at least 16GB of memory
I think we can do without for now :)
