Improved the efficiency of evars traverals thanks to a split of
evar_map into a map for defined evars and a map for undefined evars.
Even before Spiwack's new proof engine, some Evd.fold were very
costly, e.g. in check_evars or progress_evar_map. With the new proof
engine, undefined evars traversals are apparently even more common (at
least, it improves significantly the complexity of some calls to omega
in JordanCurveTheorem - a new factor 5-7 after the factor 5-6 obtained
by removal of evar_merge in clenv_fchain in commit 13007, arriving to
figures comparable to the 8.3 ones).
