Created attachment 28943
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28943
updated #c9 patch

And last, a non-working updated version of the #c9 patch.
The find_base_term* part of it probably would work, it is just a forward port
of the earlier patch to new vec C++ish stuff, but without the --param patch the
go1 testcase was still very slow, spending too much time in get_addr (again,
walking many thousands long locs list of a few VALUEs all the time), this
another cache helped that to get within 10 minutes of compile time, but it
didn't pass bootstrap, many compilations during bootstrap got stuck for many
minutes.  So, I'm providing this just for completeness.
