Fixed issue with ssl deduplication

Due to ssl deduplication in the event of parameters that can be
vectored with ssls, it can happen that there are 2 ssl with the
same inx. If so there will be double free if these are placed both
in the freeable ssls.  So do not put duplicate inxes in freeable
ssls.
Fixed issue with deduplication

If ssl is qr global, it is not a vector and needs no deduplication
if occurs as param but does need a copy if in a gby key, as these
are always vectored

Added new flag enable_joins_only
Fixed issue with running out of memory before making first plan in subq
Fixed issue with IN pref on a col and an eq on the same

If there is an in pred on a col and an eq on the same the in is
likely redundant and should not lead to each value in the in being
counted as an execution of the operator. This is only if the in
is by index and there is no other conds
