Don't store the data for case statements of the form `LHS ... RHS` if not needed.
This cuts the size of `CaseStmt` by 1 pointer + 1 `SourceLocation` in
the common case.

Also use the newly available space in the bit-fields of `Stmt` to store the
keyword location of `SwitchCase` and move the small accessor
`SwitchCase::getSubStmt` to the header.
