Added the code processing on expressions for applying multiple equalities. Many files: Post-merge fixes for Item_equal patch. item_cmpfunc.cc: Post-merge fixes for Item_equal patch. Fixed a problem when an equality field=const cannot be applied to the predicate P(field,c) for constant propagation as a conversion of field is needed. item.h, item.cc: Fixed a problem when an equality field=const cannot be applied to the predicate P(field,c) for constant propagation as a conversion of field is needed. mysql-test/r/func_test.result: Post-merge fixes for Item_equal patch. mysql-test/r/index_merge.result: Post-merge fixes for Item_equal patch. mysql-test/r/join_nested.result: Post-merge fixes for Item_equal patch. mysql-test/r/range.result: Post-merge fixes for Item_equal patch. sql/item.cc: Fixed a problem when an equality field=const cannot be applied to the predicate P(field,c) for constant propagation as a conversion of field is needed. sql/item.h: Fixed a problem when an equality field=const cannot be applied to the predicate P(field,c) for constant propagation as a conversion of field is needed. sql/item_cmpfunc.cc: Post-merge fixes for Item_equal patch.
