There is a precedant: .pushsection/.popsection (MCStreamer::SectionStack). With .push_align_branch/.pop_align_branch, we probably don't need the 'switch-to-default' action. I don't know how likely we may ever need nested states (e.g. an `.include` directive inside an .align_branch region where the included file has own idea about branch alignment), but .push/.pop does not seem to be more complex than disable/enable/default.
