Subject: [evarconv] solve_simple_eqn is weaker than miller pattern (fix #9663)

In particular evar_eqappr_x tries to find a miller pattern on both sides,
while the fast path for evars tries solve_simple_eqn in one direction
only. So if you have (Evar-not-miller = Evar-miller) the code was not
trying to solve the RHS.
