Patch that wires up ix86_expand_convert_sign_didf_sse

For some reason, ix86_expand_convert_sign_didf_sse is not wired into floatdi
expander, so we never generate sse sequence for 32bit floatdi.

Attached patch also includes my pathetic attempt to implement
ix86_expand_convert_sign_disf_sse, but surely would need some help here...
