Allow combination of non-instant, non-rebuilding operations with changes of table options that do not require a rebuild. For example, DROP INDEX or ADD INDEX can be performed with ALGORITHM=NOCOPY together with changing such table options. Changing the table options alone would be allowed with ALGORITHM=INSTANT. INNOBASE_ALTER_NOCREATE: A new set of flags, for operations that are refused for ALGORITHM=INSTANT and do not involve creating index trees. Move ALTER_RENAME_INDEX to the proper place (INNOBASE_ALTER_INSTANT). innobase_need_rebuild(): Do not require a rebuild if INNOBASE_ALTER_NOREBUILD operations are combined with ALTER_OPTIONS. ha_innobase::prepare_inplace_alter_table(), ha_innobase::inplace_alter_table(): Use the fast path if ALTER_OPTIONS is combined with INNOBASE_ALTER_NOCREATE. In this case, the actual changes would be deferred to ha_innobase::commit_inplace_alter_table().
