Otherwise the legalizer would just scalarize everything. Support for mulhi in the targets isn't that great yet so on most targets we get exactly the same scalarized output. Add a test for x86 vector udiv. I had to disable the mulhi nodes on ARM because there aren't any patterns for it. As far as I know ARM has instructions for getting the high part of a multiply so this should be fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207315 91177308-0d34-0410-b5e6-96231b3b80d8
