Craig Topper 80f6556e8a [APInt] Remove return value from tcFullMultiply.
The description says it returns the number of words needed to represent the results. But the way it was coded it always returns (lhsWords + rhsWords) or (lhsWords + rhsWords - 1). But the result could be even smaller than that and it wouldn't tell you.

No one uses the result today so rather than try to fix it, just remove it.
