2cf1183e - Use optimized graph in Inline (essentially, making Inline recursive now). (#26489)

Use optimized graph in Inline (essentially, making Inline recursive now). (#26489) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/26489 This basically fixes Inline(recurse=true) and makes it a default. One reservation against running inlining recursively in the original implementation was that we might hit a quadratic behavior, but in this implementation it's not an issue since we're inlining only already inlined graphs and as we recursively descend the call tree we're caching graphs we've already optimized.
