New Revision: 106811

URL: http://llvm.org/viewvc/llvm-project?rev=106811&view=rev
Log:
Make sure all eliminated kills are removed from VNInfo lists.

This fixes PR7479 and PR7485. The test cases from those PRs are big, so not
included. However, PR7485 comes from self hosting on FreeBSD, so we will surely
hear about any regression.
