In commit 3086268accb51500804fad53086856d38721e11e, Ian did a quick fix to make the dataset work with floatX. But we need to think how to do it correctly in all case.

If we have floatX=float32 and we always use a datatset in float32, we should not waste memory by keeping it in float64. But there is the other way, sometimes we want to upcast it to float64 at the start but not always.
