MI-level patchpoint operands.
MI patchpoint operations take the form: [<def>], <id>, <numBytes>, <target>, <numArgs>, <cc>, ...
IR patchpoint intrinsics do not have the <cc> operand because calling convention is part of the subclass data.
SD patchpoint nodes do not have a def operand because it is part of the SDValue.
Patchpoints following the anyregcc convention are handled specially. For these, the stack map also records the location of the return value and arguments.
