* Render `if_exists` and `if_not_exists` parameters in
`CreateTableOp`, `CreateIndexOp`, `DropTableOp` and
`DropIndexOp` in an autogenerate context.
* Enhance `version_locations` parsing to handle paths containing
newlines.
* Added support for `Operations.create_table.if_not_exists` and
`Operations.drop_table.if_exists`, adding similar
functionality to render IF [NOT] EXISTS for table operations
in a similar way as with indexes.
