    coroutines: Copy attributes to the outlined functions [PR95518,PR95813]

    We had omitted the copying of function attributes, we now copy
    the used, alignment, section values from the original decal and
    the complete set of function attributes.  It is likely that
    some function attributes don't really make sense for coroutines,
    but that can be disgnosed separately. Also mark the outlined
    functions as artificial, since they are; some diagnostic
    processing tests this.
