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.
