  Log Message:
  -----------
  [AggressiveInstCombine] Ignore debug instructions when load combining (#70200)

We previously included debug instructions when counting instructions when
looking for loads to combine. This meant that the presence of debug
instructions could affect optimization, as shown in the updated testcase.

This fixes #69925.
