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
