Chris Lattner 5eee427594 Fix some bugs in SimplifyNodeWithTwoResults where it would call deletenode to ... delete a node even if it was not dead in some cases. Instead, just add it to the worklist. Also, make sure to use the CombineTo methods, as it was doing things that were unsafe: the top level combine loop could touch dangling memory. This fixes CodeGen/Generic/2008-01-25-dag-combine-mul.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46384 91177308-0d34-0410-b5e6-96231b3b80d8		2008-01-26 01:09:19 +00:00
