[MachineOutliner] Add support for target-default outlining. This adds functionality to the outliner that allows targets to specify certain functions that should be outlined from by default. If a target supports default outlining, then it specifies that in its TargetOptions. In the case that it does, and the user hasn't specified that they *never* want to outline, the outliner will be added to the pass pipeline and will run on those default functions. This is a preliminary patch for turning the outliner on by default under -Oz for AArch64. https://reviews.llvm.org/D48776 llvm-svn: 336040

[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
