I am re-building now. Martin's edge cgraph_opt streaming fix is needed and
flag_shlib needs to be set in lto-options.c
With this fixed oprofile shows that cc1plus spends a lot of time in
lookup_filed_1.

I am adding c++ maintainers to CC as this seems like relatively low hanging
fruit for noticeable compilation speedup? It tends to show in oprofile as 5-7%
of compile time.
