This hook must be implemented to lower the given call instruction, including argument and return value marshalling.
Callee is the destination of the call. It should be either a register, globaladdress, or externalsymbol.
ResTy is the type returned by the function
ResReg is the generic virtual register that the returned value should be lowered into.
ArgTys is a list of the types each member of ArgRegs has; used by the target to decide which register/stack slot should be allocated.
ArgRegs is a list of virtual registers containing each argument that needs to be passed.

This hook must be implemented to lower the incoming (formal) arguments, described by Args, for GlobalISel.
Each argument must end up in the related virtual register described by VRegs. In other words, the first argument should end up in VRegs[0], the second in VRegs[1], and so on. MIRBuilder is set to the proper insertion for the argument lowering.
