Thanks for your review!

> Let's just increase the widths unconditionally

Do you mean:

  class PseudoObjectExprBitfields {
      friend class ASTStmtReader; // deserialization
      friend class PseudoObjectExpr;
  
      unsigned : NumExprBits;
      unsigned NumSubExprs : 16;
      unsigned ResultIndex : 16;
    };
