  1. Fix negative shift left reported by UBSan 

    Follow-up of uclouvain#757

This shall have no performance impact on 2’s complement machine where
the compiler replaces the multiplication by power of two (constant) by
a left shift.
Verified at least on MacOS Xcode 7.3, same assembly generated after fix.
