  Log Message:
  -----------
  [InstCombine] combine constants by reassociating add/sub/add

This may overlap partially with the reassociate pass,
but it seems simple enough that we should try it here
in InstCombine to enable other folds.

This shows up as an opportunity and potential regression
if we improve a subtract fold with 'not' ops to be more
general.
