CompSpecType, a clone of CompSpec but in Type instead of Prop
In interfaces fields like compare_spec, a CompSpec is prefered to get
nice extraction, but then no "destruct (compare_spec .. ..)" is
possible in a Type context. Now you can say there
"destruct (CompSpec2Type (compare_spec ... ...))"
This translate to the Type variant, and make the analysis on it
(which is equivalent to analysing the comparison directly).
