[PATCH] D113772: [Analysis] Fix getNumberOfParts to return 0 when the answer is unknown

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Given that TargetLoweringBase::getTypeLegalizationCost() can currently fail, I guess this patch makes sense.  Long-term, I'm not sure we want it to fail in cases like this, but we don't need to deal with that right now.

The commit message should probably mention TypeScalarizeScalableVector somewhere.
