Funny I was just helping with a PowerPC issue dealing with that function: see
PR 42431.  shared_const_p was introduced by the merge of the Dataflow branch
but the code was outlined and the original code was introduced by Richard
Kenner back in 1992.  I don't know any more history about that function besides
that.
