  Changed paths:
    M mlir/include/mlir/IR/Operation.h

  Log Message:
  [mlir] support isa/cast/dyn_cast<Operation *>(operation)

This enables one to write generic code that can be instantiated for both
specific operation classes and the common base class without
specialization. Examples include functions that take/return ops, such

template <typename FnTy>
void applyIf(FnTy &&lambda, ...) {
  for (Operation *op : ...) {
    auto specific = dyn_cast<function_traits<FnTy>::template arg_t<0>>(op);
    if (specific)

that would otherwise need to rely on template specialization to support
lambdas that take specific operations and those that take `Operation *`.
