Protect against "it's unifiable, if you solve some unsolvable constraints" behavior of evar_conv_x,
getting more common after patch on evars and eta. The main problem is that ?X = C[?X] problems get
postponed now, when they failed earlier before (rendering the algorithm incomplete, e.g. on ?X = \y. ?X y).
A notion of "rigid/strongly rigid" occurrences would give a better fix.
