  Log Message:
  [LV] Move code from vectorizeMemoryInstruction to recipe's execute().

The code in widenMemoryInstruction has already been transitioned
to only rely on information provided by VPWidenMemoryInstructionRecipe

Moving the code directly to VPWidenMemoryInstructionRecipe::execute
completes the transition for the recipe.

It provides the following advantages:

1. Less indirection, easier to see what's going on.
2. Removes accesses to fields of ILV.

2) in particular ensures that no dependencies on
fields in ILV for vector code generation are re-introduced.
