Add api for recursively analyzing function calls (#73329)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73329
There is a quantization use case for having better alias analysis with function calls remaining. This does the relatively dumb approach of getting the inlined graph of each function call, and then analyzing that subgraph. Since we need a unique single analysis of every `Value*`, for every function call make a copy of the graph for every analysis past the first. This is relatively slow, but given the limited use case here should work well enough (and is no slower than calling the inlining pass).
