Manual merge between bug#46362 and bug#20577.
sql/opt_range.cc: Removed duplicate code (if statement must have been duplicated during earlier merge). sql/sql_partition.cc: After mergeing bug#46362 and bug#20577, the NULL partition was also searched when col = const, fixed by checking if = or range.
