The raw `OpView` classes are used to bypass the constructors of `OpView` subclasses, but having a separate class can create some confusing behaviour, e.g.: ``` op = MyOp(...) # fails, lhs is 'MyOp', rhs is '_MyOp' assert type(op) == type(op.operation.opview) ``` Instead we can use `__new__` to achieve the same thing without a separate class: ``` my_op = MyOp.__new__(MyOp) OpView.__init__(my_op, op) ``` Reviewed By: stellaraccident Differential Revision: https://reviews.llvm.org/D143830
