Nikita Popov 8851ea64a5 [ConstantHoist] Fix APInt ctor assertion ...

The result here may require truncation. Fix this by removing the
calculateOffsetDiff() helper entirely. As far as I can tell, this
code does not actually have to deal with different bitwidths.

findBaseConstants() will produce ranges of constants with equal
types, which is what maximizeConstantsInRange() will then work
on.
