Justin Bogner d237e834a8 Transforms: Use getFirstNonPHI to set the insertion point for PHIs
We were previously using getFirstInsertionPt to insert PHI
instructions when vectorizing, but getFirstInsertionPt also skips past
landingpads, causing this to generate invalid IR.

We can avoid this issue by using getFirstNonPHI instead.
