--- Comment #1 from bjorn.a.petters...@ericsson.com ---
I see the assertion failure with r372137, but not with r372138 (and later). I'm
currently at r372709. So I think we can assume that r372138 resolves this PR.

Commit msg says:

commit 4e9082ef95db5d760df4cce00a4351fa122176d6 (HEAD)

    [MemorySSA] Fix phi insertion when inserting a def.

    Summary:
    When inserting a Def, the current algorithm is walking edges backward
    and inserting new Phis where needed. There may be additional Phis needed
    in the IDF of the newly inserted Def and Phis.
    Adding Phis in the IDF of the Def was added ina  previous patch, but we
    may also need other Phis in the IDF of the newly added Phis.
