With the advent of CPUs in the device maps, and to be more generic (e.g., to support AMD GPUs), and to avoid conversions when passing to Future and RRef and such, it's easier to use Devices instead of DeviceIndices. This started by just migrating the TensorPipe agent but the RPC layer is quite intertwined so I had to migrate a lot of stuff.

pointers instead of CallArgs. That helps to reduce the invocation

Inlining is great if LLVM's CSE kicks in; but if a kernel has multiple outputs
(and thus multiple loops), CSE has no chance.
So, this pass "horizontally" fuses the output loops together so that CSE can go
to town. Essentially we want to turn
```
for (...) {
output_1[] = some_complicated_expr...
}
for (...) {
output_2[] = some_complicated_expr...
}
```
Into:
```
for (...) {
output_1[] = complicated_expr
output_2[] = complicated_expr. // llvm cse should take care of this
}
```

Summary:
This PR allows fusing loops whose bounds are specified as expressions that are equal.
For example:
```
for (int j = 0; j < M + N; j++) {
A[j] = 10 * j;
}
for (int k = 0; k < M + N; k++) {
B[k] = 20 * k;
}
```
`fuseLoops(j, k)` is possible since the stop bounds of the two loops are equal though they are different `Expr*` and will result in:
```
for (int j = 0; j < M + N; j++) {
A[j] = 10 * j;
B[j] = 20 * j;
}
```

This reverts commit ad17fadbfc (D27786457).
The big annoyance here is that depending on the threading mode you may not be
able to toggle num_threads at will, so the fusion tests won't fail.
I hate this solution, but I'm adding a secondary override for the TE fuser.
Now you need to both turn on fusion (_jit_override_can_fuse_on_cpu), and you're
OK if you're running with 1 thread, or you can add
`_jit_set_texpr_parallel_cpu_enabled` to enable it anyways.
This is (a) mainly for tests, since a real user probably won't fiddle aimlessly
with the thread count, and (b) will go away once NNC's threading support is
fully baked.

This PR does not add support for `padding_idx` for quantized or ONNX `EmbeddingBag` for opset10/11 (opset9 is supported). In these cases, an error is thrown if `padding_idx` is provided.

With this change `rfactor` only affects the passed loop and its body
never touching anything outside (that was a rootcause of a bug with the
previous implementation). Also, we don't have an `insertion_point`
parameter anymore - its meaning was vague, and the effect of it
should've been achievable with other transformations anyway.
The new `rfactor` semantics is as follows:
```
Requirements:
* S is the reduction store
* S is the only statement in the innermost loop
* There is at least two reduction arguments in S
* OUTER_REDUCTION_FOR loop corresponds to the outermost reduction variable
used in the store and all other reduction variables are index variables of
children loops of OUTER_REDUCTION_FOR
* OUTER_REDUCTION_FOR is a perfect loop nest, i.e. it has only loops
corresponding to the other reduction variables and the store, nested into
each other
What it does:
* Introduce a new buffer with an extra dimension of a size equal to the
span of the loop OUTER_REDUCTION_FOR (the new buffer is returned via
RFAC_BUF_PTR)
* Insert an initialization store for the new buffer in
OUTER_REDUCTION_FOR before its nested loop
* Replace the reduction store to the original buffer with the reduction
store to the temp buffer, removing the index var of OUTER_REDUCTION_FOR
from reduction arguments
* Insert a final reduction store over the extra dimension of the new
buffer to the original buffer
* Returns TRUE if the transformation succeeded and FALSE otherwise
Example:
Original IR:
S1: for i # normal axis
S2: X[i] = 0
S3: for j # reduction axis
S4: for k # reduction axis
S5: X[i] = ReduceOp(X[i] + Y[i,j,k], reduce_axis={j,k})
After RFACTOR(S5, S3)
S1: for i # normal axis
S2: X[i] = 0
S3: for j # reduction axis for X, normal axis for X_rfac
X_rfac[i,j] = 0
S4: for k # reduction axis
X_rfac[i,j] = ReduceOp(X_rfac[i,j] + Y[i,j,k], reduce_axis={k})
X[i] = ReduceOp(X[i] + X_rfac[i,j], reduce_axis={j})

A few important points about InferenceMode behavior:
1. All tensors created in InferenceMode are inference tensors except for view ops.
- view ops produce output has the same is_inference_tensor property as their input.
Namely view of normal tensor inside InferenceMode produce a normal tensor, which is
exactly the same as creating a view inside NoGradMode. And view of
inference tensor outside InferenceMode produce inference tensor as output.
2. All ops are allowed inside InferenceMode, faster than normal mode.
3. Inference tensor cannot be saved for backward.

Added needsOutputs support to RecordFunction, improved ObserverUtil functions to handle list data. Minor refactor names to be consistent.
To get output data from kernel calls, we need to temporarily capture them before passing them to the record function. Then the results are released to function return. We handle two cases, for unboxed and boxed kernels. The boxed version is fairly simple since all outputs are stored in the stack object. For unboxed kernel calls, we added a `ReturnValue` utility class to properly handle the different return values of unboxed kernels.
For optimization, this intermediate capture is only enabled for observers that request `needsOutputs(true)` and should not affect other observers or when the observer is not enabled.
