Added missing semicolons in sql_yacc.yy, and did a style clean-up. 

Note: Textual changes only, no functional changes.


sql/sql_yacc.yy:
  Added missing semicolons to quiet yacc warnings.
  Also did a general style clean-up, placing clause terminating semicolons in
  a consistent way (on separate lines).
