[VPlan] Remove redundant blocks by merging them into predecessors.

Add and run VPlan transform to fold blocks with a single predecessor
into the predecessor. This remove redundant blocks and addresses a TODO
to replace special handling for the vector latch VPBB.

Recommit "[VPlan] Add VPDerivedIVRecipe, use for VPScalarIVStepsRecipe."

This reverts commit bf15f1e489aa2f1ac13268c9081a992a8963eb5b.

The updated version fixes a crash by checking the induction kind instead
of the opcode; for integer inductions, the step is always added, but the
opcode might not be set.
