Summary:
The PR clang-formats everything in `torch/csrc/jit/` and adds it to the pre-commit hook.
Here is a list of non-mechanical changes:
- I went over each file and fixed up whenever I could tell that clang-format was clobbering comment formatting.
- Made the macros in register_prim_ops a little more clang-format friendly by omitting trailing commas
- Refactored autodiff.cpp to use a helper class with explicit state rather than a bunch of capturing lambdas
- Small improvements to the precommit hook clang-format

Summary:
Anywhere we used #include "foo.h", we now say #include <foo.h>
Paths are adjusted to be rooted out of aten/src, torch/lib, or
the root level directory.
I modified CMakeLists.txt by hand to remove TH and THC from
the include paths.
I used the following script to do the canonicalization:
```
import subprocess
import re
import os.path
files = subprocess.check_output(['git', 'ls-files']).decode('utf-8').rstrip().split('\n')
for fn in files:
if not any(fn.endswith(suff) for suff in ['.cu', '.cpp', '.in', '.h', '.hpp', '.cu', '.cuh', '.cc']):
continue
if not any(fn.startswith(pref) for pref in ["aten/", "torch/"]):
continue
with open(fn, 'r') as f:
c = f.read()
def fmt(p):
return "#include <{}>".format(p)
def repl(m):
p = m.group(1)
if p in ["dlfcn.h", "unistd.h", "nvrtc.h", "cuda.h", "cuda_runtime.h", "cstdint", "cudnn.h", "Python.h", "cusparse.h", "cuda_runtime_api.h", "cuda_fp16.h", "cublas_v2.h", "stdint.h", "curand_kernel.h"]:
return fmt(p)
if any(p.startswith(pref) for pref in ["torch/csrc", "c10/", "ATen/", "caffe2/", "TH/", "THC/", "Eigen/", "gtest/", "zdl/", "gloo/", "onnx/", "miopen/"]):
return fmt(p)
for root in ["aten/src", "torch/lib", ""]:
for bad_root in [os.path.dirname(fn), "aten/src/TH", "aten/src/THC", "torch/csrc"]:
new_p = os.path.relpath(os.path.join(bad_root, p), root)
if not new_p.startswith("../") and (os.path.exists(os.path.join(root, new_p)) or os.path.exists(os.path.join(root, new_p + ".in"))):
return fmt(new_p)
print("ERROR: ", fn, p)
return m.group(0)
new_c = re.sub(r'#include "([^"]+)"', repl, c)
if new_c != c:
print(fn)
with open(fn, 'w') as f:
f.write(new_c)
```

* Namespaced symbols
- Our interned strings now have structure, "ns::symname" rather than just
"symname" before. We support efficient namespace testing for uniques
by encoding the namespace in one byte in the Symbol internal representation.
See torch/csrc/jit/interned_strings.h for a more in-depth implementation
discussion.
- All uses of ksymbol are now attr::symbol (or some appropriate namespace).
The valid namespaces are prim, attr, onnx and aten.
- Symbol is bound in Python as a qualified string "attr::symbol", EXCEPT for the
attribute setting/getting API, whose symbols must always be attr
symbols; they get special cased to assume strings are passed.
There's a little bit of naughtiness in the implementation, maybe you know
how to solve it.
- However, the g.op() convenience function assumes that you're generating
ONNX operators, unless you explicitly qualify.
- All ATen operators and nodes have built-in interned strings generated
for them, so you should never have to write a string literal ever again.
The tracing code is adjusted to use it.
- ONNX exporter now properly tests to see that all operators are in
onnx namespace before accepting the export. This is way more
robust than the previous exporter, which would be willing to
export capitalized operators which were not actually ONNX operators.
- A slight organizational change for symbolic.py; this module now ONLY
contains aten operators. In particular, the exporter for Constant
has moved into utils.py (along with Undefined, from the C++ side),
since primitive ops get "special treatment."
- The un-inplacing logic in recording is more robust, so that we don't
delete a trailing underscore from __and__. This never affected us
before because we didn't have any tests for it.

* Add Python function calls to script
* Script compiler gains a `Resolver` object that runs when it does not understand a function call. This decouples the python resolution from the conversion to IR.
This deletes most of the dead Tensor code paths, including the TensorMethods cwrap and generic/Tensor.cpp.
This also moves the THNN.cwrap/.cpp generation to generate_code which can use ninja if installed.
* Improve Variable interface
* Address comments from @apaszke and @colesbury
* string ::operator= is not noexcept
* Remove ir.h from tracer_state.h to improve build times
* Make Variable a struct and pack SavedVariable fields
* Implement as_variable_ref
* grad_fn_ptr() -> grad_fn_unsafe()
* Reduce hackiness of set_type hack
* Include variable.h and edge.h in tracer_state.h because it uses them
* class Variable -> struct Variable because Windows cant even
* Make Variable::output_nr uint32_t instead of int
* Add comment about tracing state
* Replaced more static_cast<Variable&> and improve docs
* Remove SavedVariable destructor and construct members in init list
* Clarify docs for Variable
* Variable::set_version -> set_version_counter
This adds the initial implementation of graph executor for the new JIT design. It includes a few python tests ensuring that nograd, backward, and double-backward cases work for simple examples and some corner cases. More work needs to be done to performance optimize as there are many extra copies and places where we hold onto variables longer than we should. These are noted in the comments.
Previous Symbol was just a uint32_t and we converts symbolToString and
stringToSymbol. Now Symbol is a struct with a toString method, and
constructors from either BuiltinSymbols enums (e.g. kParam) or strings.
Symbol is convertible to a uint32_t to ensure it can still be used in
switch statement BuiltinSymbol case branches.
This started off as a minor fix based on Adam's question, "why is printing
a graph not const" and snowballed into a giant yak shaving exercise.
- The Graph and Node APIs now uniformly enforce deep constness; e.g., if you
get a const Node* or const Graph*, it is not possible to get a non-const
Node*/Graph* somewhere else in the graph (even though the member variables
of these are non-const. Hooray for private access specifier.)
- A big pile of functions got const versions, most notably the printing
functions, and functions for accessing inputs().
- REALLY IMPORTANT, BC-BREAKING CHANGE: inputs() now returns a COPY of the
inputs, rather than a reference to the underlying. I was forced to do this
because there is no way to portably turn a std::vector<Node*> into a
std::vector<const Node*>, which is necessary to provide a const-correct
version of inputs() that enforces deep const-correctness. I then justified
this choice to myself with the observation that outputs() returned a
copy (by necessity), so this makes the API more uniform.
But making this change uncovered two very subtle bugs:
1. If you change functions from returning a reference to returning a copy,
the idiom node->inputs().begin() is no longer valid, because the memory
the iterator points to immediately becomes invalid. THIS SUCKS.
Honestly, we should add a lint rule rejecting calling begin()/end() on
temporaries because this is very dangerous. To excise this pattern from
the codebase, I added begin() and end() methods to Graph, so that we got
rid of the graph->nodes().begin() idiom, which happens to be sound,
despite not returning a reference, because graph_node_list is a
non-owning reference.
2. pybind11 doesn't handle std::vector<Node*> cast out of the box.
Fortunately, I found a simple fix in the GitHub issues tracker
that involved adding an extra type converter. And yes, this
does mean that outputs() in Python never worked correctly.
- New const_graph_node_list, which is a graph_node_list that gives you const
Node*
There are some more miscellaneous improvements:
- Applied CR comment fixes on export.cpp; using replaceInput, and renaming
variables for clarity.
- assertValidInput helper method added, and applied to replaceInput
- Use an explicit function to print THPObjectPtr, otherwise we get
the wrong overload.
