Prior to this patch, the MCVs for text columns was not being passed to ORCA. Hence the cardinality estimation for predicates involving text was inaccurate and led to sub optimal plans being picked. This patch allows the MCVs to be passed in to ORCA so that it can now estimate the cardinality using MCVs equal and not equal operators for text columns.
