Bug #57276 mysqltest: add support for simple compares in if/while conditions

      Added more parsing in do_block()
      Limitation: left operand must be variable
      Also changed var_set_int from 57036 to var_check_int
      Added tests to mysqltest.test
      Some tests can now be simplified but will take this later
      Updated after comments, now white space around operator not needed
