[PATCH] D58006: [SelectionDAG] Extract [US]MULO expansion into TL method; NFC

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

@spatel This is needed for D57997 <https://reviews.llvm.org/D57997>, to allow mulo expansion during vector op legalization, as the (potentially) resulting unrolled scalar ops still need to be legalized subsequently.
