  Log Message:
  -----------
  [VPlan] Use one VPWidenRecipe per original IR instruction. (NFC).

This patch changes VPWidenRecipe to only store a single original IR
instruction. This is the first required step towards modeling it's
operands as VPValues and also towards breaking it up into a
VPInstruction.

Discussed as part of D74695.
