[clang] Fix crash caused by PseudoObjectExprBitfields::NumSubExprs overflow
This patch makes the bit-fields wider, and also implement a small optimization for `PseudoObjectExprBitfields`, when there is no result in `PseudoObjectExpr`, we use 32 bits to store the number of subexpressions, otherwise, we use 16 bits to store the number of subexpressions, and use 16 bits to store the result indexes.
