The lower 16 bits are used to specify which constraints are set.
The higher 16 bits are used to specify the value of constraints (4 bits each).

| int16_t llvm::MCOperandInfo::RegClass |
This specifies the register class enumeration of the operand if the operand is a register.
If isLookupPtrRegClass is set, then this is an index that is passed to TargetRegisterInfo::getPointerRegClass(x) to get a dynamic register class.
