Erik Eckstein 7afa419dd4 SIL: improve inline bitfields in SILNode, SILBasicBlock and Operand ...

* Let the customBits and lastInitializedBitfieldID share a single uint64_t. This increases the number of available bits in SILNode and Operand from 8 to 20. Also, it simplifies the Operand class because no PointerIntPairs are used anymore to store the operand pointer fields.
* Instead make the "deleted" flag a separate bool field in SILNode (instead of encoding it with the sign of lastInitializedBitfieldID). Another simplification
* Enable important invariant checks also in release builds by using `require` instead of `assert`. Not catching such errors in release builds would be a disaster.
* Let the Swift optimization passes use all the available bits and not only a fixed amount of 8 (SILNode) and 16 (SILBasicBlock).
