Summary: This change allows us to add arg1 logging support to functions through the special case list provided through -fxray-always-instrument=. This is useful for adding arg1 logging to functions that are either in headers that users don't have control over (i.e. cannot change the source) or would rather not do. It only takes effect when the pattern is matched through the "fun:" special case, as a category.
