Florian Hahn a5bb4a3b4d [VPlan] Replace CondBit with BranchOnCond VPInstruction. ...

This patch removes CondBit and Predicate from VPBasicBlock. To do so,
the patch introduces a new branch-on-cond VPInstruction opcode to model
a branch on a condition explicitly.

This addresses a long-standing TODO/FIXME that blocks shouldn't be users
of VPValues. Those extra users can cause issues for VPValue-based
analyses that don't expect blocks. Addressing this fixme should allow us
to re-introduce 266ea446ab.

The generic branch opcode can also be used in follow-up patches.

Depends on D123005.
