[PATCH] D140210: [IPSCCP] Enable specialization of functions.

[Nikita Popov via Phabricator via llvm-commits]

I tested this against rust: https://perf.rust-lang.org/compare.html?start=413335368bf860e701f6365b0f2f0fa4d7f85b9a&end=70212127e0974013f7e031861d421356e85b0e27&stat=instructions%3Au The results look unconcerning to me, there are no major changes in compile-time, memory usage or binary size. I guess the heuristics are sufficiently conservative to not cause problems. And it didn't crash on any of the benchmarks, so that's reassuring...

So this is fine to go ahead from my side, but I did not review the implementation at all.
