  -----------
  BPF: Fix misfolding subregisters

This would end up introducing a copy between registers
with mismatched sizes previously. Defends against verifier
failures in a future change.

The actual transform here should be deleted. Optimizations should
not be trying to introduce SUBREG_TO_REG.
