[MachineOutliner] Add always and never options to -enable-machine-outliner This is a recommit of r335887, which was erroneously committed earlier. To enable the MachineOutliner by default on AArch64, we need to be able to disable the MachineOutliner and also provide an option to "always" enable the outliner. This adds that capability. It allows the user to still use the old -enable-machine-outliner option, which defaults to "always". This is building up to allowing the user to specify "always" versus the target default outlining behaviour. https://reviews.llvm.org/D48682 llvm-svn: 335986

[MachineOutliner] Never add the outliner in -O0 This is a recommit of r335879. We shouldn't add the outliner when compiling at -O0 even if -enable-machine-outliner is passed in. This makes sure that we don't add it in this case. This also removes -O0 from the outliner DWARF test. llvm-svn: 335930
