Papering over this bug gets us as far as reaching

void
cgraph_mark_needed_node (struct cgraph_node *node)
{
  node-needed = 1;
  gcc_assert (!node-global.inlined_to);

So, why do we complain here:

  gcc_assert (node-global.inlined_to
  || !gimple_has_body_p (decl)
  || DECL_EXTERNAL (decl));

for

read_error/5(-1) @0xb7d33200 (clone
of read_error/4) availability:not_available (15 after inlining) (6 after
inlining) needed reachable body externally_visible finalized
  called by: fill_inbuf/2 (0.00 per call) 
  calls: 

a clone which is not available (but needed and externally_visible?!).

I'm reducing it from 164.gzip with -O3 -ffast-math -fwhopr -fwhole-program.
