  -----------
  [Scalarizer] Use correct key for ExtractValueInst gather (#149855)

Fixes #149345

Effectively no-op pairs of insertelement-extractelement instructions
were being created due to the ExtractValueInst visitor in the Scalarizer
storing its scalarized result into the Scattered map using an incorrect
key (specifically the type used in the key).
This PR fixes this issue.
