[v3] Update Solaris baselines for GCC 4.7

[Rainer Orth]

Just as for the GCC 4.6 release, I plan to update the Solaris baselines
before 4.7.0 ships.  The following untested patch (simply created with
make new-abi-baseline) would do so, but I don't propose installing it
yet for several reasons:

* I'd like the baselines to be identical to the release, and there may
  well be more changes between now and then.

* I already noticed several errors that need to be fixed for the
  release.

* For the first time, there are differences between the baselines with
  Sun as (which doesn't support TLS before Solaris 10) and GNU as (which
  does), so we get different libstdc++.so interfaces depending on the
  toolset used.

On to the errors:

* I noticed several new symbols being placed into GLIBCXX_3.4.5, which
  also happens with gld and thus isn't an issue with Sun ld versioning
  support.  Adding to an old version is not supposed to happen and must
  be fixed.

+FUNC:_ZNSt19istreambuf_iteratorIwSt11char_traitsIwEEppEv@@GLIBCXX_3.4.5

* There's quite a number of additions to 3.4.11:

* I'm also getting additions to 3.4.15, which should be fixed by now:

Apart from that, baselines with Sun as (emutls) and GNU as (native TLS)
differ on Solaris 8:

This hasn't happened before.  While the additions with gas are ok, the
removals are not.

Thoughts?
