Michael Kuperstein 247caf8b05 [InstCombine] scalarizePHI should not assume the code it sees has been CSE'd ... scalarizePHI only looked for phis that have exactly two uses - the "latch" use, and an extract. Unfortunately, we can not assume all equivalent extracts are CSE'd, since InstCombine itself may create an extract which is a duplicate of an existing one. This extends it to handle several distinct extracts from the same index. This should fix at least some of the performance regressions from PR27988.
