This commit makes it so that if you outline a def of some register, then the call instruction created by the outliner actually reflects that the register is defined by the call. It also makes it so that outlined functions don't have the TracksLiveness property. Outlined calls shouldn't break liveness assumptions that someone might make. This also un-XFAILs the noredzone test, and updates the calls test. llvm-svn: 331095
