Sorry, it was my misses when I added regression test cases.

The attached patches are:

part-1: only regression test of DROP [IF EXISTS] on unmodified master
part-2: drop statement reworks that uses T_DropStmt
part-3: drop statement reworks for other object classes

Unfortunately, the part-3 had to change regression test portion a bit,
because ...
 - Unmodified master does not print ", skipping" when we tried to
   drop non-existence operator class with IF EXISTS.
 - Unmodified master raised an error, not notice, when we tried to
   drop non-existence operator family with IF EXISTS.
   Is it a bug to be fixed, isn't it?
