riccibruno added a dependency: D54325: [AST] Pack CXXBoolLiteralExpr, CXXNullPtrLiteralExpr and CXXThisExpr.

Use the newly available space in the bit-fields of `Stmt` to store
some data from `CXXThrowExpr`, `CXXDefaultArgExpr`
and `CXXDefaultInitExpr`. This saves 1 pointer for each of these classes.
