powerpc testsuite regressions (was Re: Bootstrap miscomparison on mainline with checking disabled)

[Andrew Pinski]

We are still having these regressions on powerpc-unknown-linux-gnu.
They happen at -O0 and only on ppc, so I doubt they're related to the
phiopt changes.  The errors are all similar, we are not emitting some
functions that the linker is looking for.
These may be related to cgraph changes.  Zack, could you check these
out?  Your changes to cgraph.c are the only thing I can think of that
may be causing these errors.

I think I know what is going on and how to fix it.

cgraph_mark_needed_node used to be called from mark_referenced which  
made
the function be in the output queue.  Now cgraph_mark_needed_node is not
called when assembling the name (unlike most targets which call  
output_addr_const
rs6000 does not).

OK? Bootstrapped on powerpc-apple-darwin with no regressions.

Thanks,
Andrew Pinski
