So today runs are complette.  Thanks to Richi who fixed ICE in symtab merging
that affected perl and GCC.  With vortex problem was that in addition to
-fno-strict-aliasing it is writting to closed files that cause ICE depending on
partiuclar glibc version.

Comparing 
http://gcc.opensuse.org/SPEC/CINT/sb-frescobaldi.suse.de-fdo-64-FDO/recent.html
vortex is 2036 with -O2 -flto, 2438 with -O2 -flto and FDO (so about 20% 
improvement)
http://gcc.opensuse.org/SPEC/CINT/sb-frescobaldi.suse.de-head-64/list.html
has -O2 runs without LTO that is 1859, so 31% for LTO+FDO, 10% LTO.

Any idea if it is one of value transforms or just edge profile making the
difference?  There are some cases of write only globals we can constant
propagate with -fwhole-program in SPEC, but I think it is parser.
