[hsa-branch] Fix ICE in binds_to_current_def_p

[Martin Jambor]

Hi,

we have found out that when building a shared object file with
pure/const HSA functions in them, we hit an assert in
binds_to_current_def_p.  The reason is that we are creating a clone
for the HSA implementation and even though normally clones are
private, ours isn't and so we need to set back not only the
TREE_PUBLIC flag but also the cgraph externally_visible flag.

I will commit it to the branch and queue for trunk for later.

Thanks,

Martin

        to the node.
