Florian Hahn 11dccf8d3a Recommit "[SCEV] Look through single value PHIs." 
This commit was originally because it was suspected to cause a crash,
but a reproducer did not surface.

A crash that was exposed by this change was fixed in 1d8f2e52925b.

This reverts the revert commit 0581c0b0eeba03da590d1176a4580cf9b9e8d1e3.
