- Remove 'dummy_for_valgrind' overrun marker as this doesn't help much. The element also distorts the sizes of objects a bit, which makes it harder to calculate gain in object sizes when doing size optimizations. - Replace usage of thd_get_current_thd() with _current_thd() - Avoid one extra call indirection when using thd_get_current_thd(), which is used by Sql_alloc, by replacing it with _current_thd()
