MI-level Statepoint operands.

Statepoint operands take the form: , , , , [call arguments...], StackMaps::ConstantOp, , StackMaps::ConstantOp, , StackMaps::ConstantOp, , [deopt args...], StackMaps::ConstantOp, , [gc pointer args...], StackMaps::ConstantOp, , [gc allocas args...], StackMaps::ConstantOp, , [base/derived pairs] base/derived pairs in gc map are logical indices into section. All gc pointers assigned to VRegs produce new value (in form of MI Def operand) and are tied to it.
