Sean Silva 122cae2ee3 Add aten::len.t, aten::size, and aten::gt.int primitive ops
Also add some canonicalizations that finally reduce ResNet down to a
single block.

Sean Silva 55c3cc6624 Add recognition/folder/lowering for aten::__is__, aten::ne.int, and aten::dim
Interestingly, TorchScript has its own op (`torch::jit::Operator`)
registry separate from the dispatcher (it is a superset of the
dispatcher).

This is where the "prim" ops and some "aten" ops (that should probably
be renamed to "prim") live. In particular, `aten::__is__` is in that
latter category of "aten but really prim". This registry is also the
source of truth for what the TorchScript interpreter calls into when it
executes.

The bulk of the "not part of the dispatcher" ops live in
09feb5f579/torch/csrc/jit/runtime/register_prim_ops.cpp (L82)

And the registry itself lives in:
09feb5f579/torch/csrc/jit/runtime/operator.cpp (L196)

This fold further reduces the IR of ResNet by folding away some
more not-taken branches. These not-taken branches in ResNet require
first-class handling of the list type which we don't yet have on any
backend.
