Not only is this change usually shorter and more readable, it also can yield better performance. size() is not always a constant time operation (such as on LinkedLists), but empty() always is.

**BC Breaking Note**
This PR breaks C++ API backward compatibility for `at::std`. A call that has argument types `at::std(Tensor, OptionalIntArrayRef, int64_t, bool)` used to resolve to the `std.correction` overload, but now it resolves to the `std.dim` overload. In order to call the `std.correction` overload, the `int64_t` argument can be wrapped in a `c10::optional`, so that the call has the form `at::std(Tensor, OptionalIntArrayRef, optional<int64_t>, bool)`. The same is true for the corresponding arguments of the `std.out` and `std.correction_out` overloads of `at::std_out`.

Summary:
Turn on layer_norm in autodiff
https://github.com/pytorch/pytorch/issues/67732 should have fixed the previously issue exposed by enabling layer_norm in autodiff.

Summary:
Adds native_dropout to have a reasonable target for torchscript in auto diff. native_dropout has scale and train as arguments in its signature, this makes native_dropout more consistent with other operators and removes conditionals in the autodiff definition.

Summary:
Adds mixed precision autocasting support between fp32/fp16 to torchscript/JIT. More in depth descriptoin can be found at [torch/csrc/jit/JIT-AUTOCAST.md](https://github.com/pytorch/pytorch/pull/63939/files#diff-1f1772aaa508841c5bb58b74ab98f49a1e577612cd9ea5c386c8714a75db830b)
This PR implemented an autocast optimization pass that inserts casting ops per AMP rule (torch/csrc/jit/passes/autocast.cpp), that mimics the behavior of eager autocast. The pass also takes into consideration the context of `torch.cuda.amp.autocast` and only inserts casting ops within the enabled context manager, giving feature parity as with eager amp autocast.
We currently provide JIT AMP autocast as a prototyping feature, so it is default off and could be turned on via `torch._C._jit_set_autocast_mode(True)`
The JIT support for autocast is subject to different constraints compared to the eager mode implementation (mostly related to the fact that TorchScript is statically typed), restriction on the user facing python code is described in doc torch/csrc/jit/JIT-AUTOCAST.md
This is a prototype, there are also implementation limitation that's necessary to keep this PR small and get something functioning quickly on upstream, so we can iterate on designs.
Few limitation/challenge that is not properly resolved in this PR:
1. Autocast inserts cast operation, which would have impact on scalar type of output tensor feeding downstream operations. We are not currently propagating the updated scalar types, this would give issues/wrong results on operations in promotion rules.
2. Backward for autodiff in JIT misses the casting of dgrad to input scalar type, as what autograd does in eager. This forces us to explicitly mark the casting operation for certain operations (e.g. binary ops), otherwise, we might be feeding dgrad with mismatch scalar type to input. This could potentially break gradient function consuming dgrad. (e.g. gemm backwards, which assumes grad_output to be of same scalar type as input')
3. `torch.autocast` api has an optional argument `dtype` which is not currently supported in the JIT autocast and we require a static value.

Graph is an implementation detail. If user wants to get access to the
underlying graph, they should be able to explicitly dynamic cast instead.

Summary:
1. extend autodiff by adding entry for layer_norm in symbolic script, we now use native_layer_norm_backward
2. added backward function `layernorm_double_backward` for `native_layer_norm_backward`, preserves double backward support for LayerNorm in autodiff/ScriptModule
3. added python test to verify autodiff on layer_norm with various configuration of optional tensors; (verify the fix in https://github.com/pytorch/pytorch/issues/49430)
