Since createplan.c no longer cares whether index operators are lossy, it has

no particular need to do get_op_opfamily_properties() while building an
indexscan plan.  Postpone that lookup until executor start.  This simplifies
createplan.c a lot more than it complicates nodeIndexscan.c, and makes things
more uniform since we already had to do it that way for RowCompare
expressions.  Should be a bit faster too, at least for plans that aren't
re-used many times, since we avoid palloc'ing and perhaps copying the
intermediate list data structure.
