Sanjoy Das 17e08f50b9 [SCEV] Strengthen SCEVExpander::isHighCostExpansion. 
Summary:

Teach `isHighCostExpansion` to consider divisions by power-of-two
constants as cheap and add a test case.  This change is needed for a new
user of `isHighCostExpansion` that will be added in a subsequent change.

Depends on D8995.
