Fix @@optimizer_switch support - Let "mysqld --help --verbose" list all optimizer options - Make it possible to add new @@optimizer_switch flags w/o causing .result changes all over the testsuite: = Remove "select @@optimizer_switch" from tests that do not need all switches = Move @@optimizer_switch-specific tests to t/optimizer_switch.test 2010-07-16 12:58:24 +04:00			`select @@optimizer_switch like '%materialization=on%';`
