  [LV] Apply sink-after & interleave-groups as VPlan transformations (NFCI)

This recommits 100e797adb433724a17c9b42b6533cd634cb796b (reverted in
009e032634b3bd7fc32071ac2344b12142286477 for failing an assert). While the
root cause was independently reverted in eaff3004019f97c64c88ab76da6b25106b659b30,
this commit includes a LIT to make sure IVDescriptor's SinkAfter logic does not
try to sink branch instructions.
