bmeurer 5d18e93bd6 Revert of binary-operator-reducer: reduce mul+div(shift) (patchset #11 id:200001 of https://codereview.chromium.org/1350223006/ ) 
Reason for revert:
This is also unsound for the reasons outlined in
https://codereview.chromium.org/1473073004/
Will help Fedor to implement a solution based on simplified operators.

>          =>  TruncateInt64ToInt32
> Int64Mul
>          =>  Int64Shr => TruncateInt64ToInt32

> Test code:
