Edward Z. Yang 90bed32b98 Introduce torch.sym_sum (#136429) 
Partially addresses https://github.com/pytorch/pytorch/issues/128150

When you have big sums of values, we end up computing long chains of
binary addition in our FX graph representation.  Not only is this ugly,
it also is quadratic, as the sympy.Add constructor is O(N) in number
of arguments.  Instead, ensure that we maintain the summation as a
single FX node so we can do the entire addition all in one go.

update_hint_regression benchmark, before and after:
