[PATCH] D37039: [SelectionDAG] Make ISD::isConstantSplatVector always return an element sized APInt.

[Craig Topper via Phabricator via llvm-commits]

craig.topper created this revision.

This partially reverts r311429 in favor of making ISD::isConstantSplatVector do something not confusing. Turns out the only other user of it was also having to deal with the weird property of it returning a smaller size.

So rather than continue to deal with this quirk everywhere, just make the interface do something sane.
