[v3] Update Solaris baselines

[Rainer Orth]

With the GCC 5 release approaching, it's time to update the Solaris
baselines again.

This patch does just that and is pretty much straightforward:

* With one exception, all new symbols are in the GLIBCXX_3.4.21 and
  CXXABI_1.3.9 versions.

* On Solaris/x86 only (obviously), we have

+OBJECT:0:CXXABI_FLOAT128
+OBJECT:16:_ZTIg@@CXXABI_FLOAT128
+OBJECT:2:_ZTSg@@CXXABI_FLOAT128
+OBJECT:32:_ZTIPKg@@CXXABI_FLOAT128
+OBJECT:32:_ZTIPg@@CXXABI_FLOAT128
+OBJECT:3:_ZTSPg@@CXXABI_FLOAT128
+OBJECT:4:_ZTSPKg@@CXXABI_FLOAT128

  For the moment (considering how late we are in the release cycle),
  I've decided to use the SPARC version for the common baseline, so
  those symbols show up as added on x86.

* On Solaris 11, there are two additonal symbols beyond those in Solaris
  10:

+FUNC:std::__cxx11::basic_stringbuf<char, std::char_traits<char>, std::allocator<char> >::~basic_stringbuf()@@GLIBCXX_3.4.21
+FUNC:std::__cxx11::basic_stringbuf<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >::~basic_stringbuf()@@GLIBCXX_3.4.21

  They are from src/c++98/complex_io.o and src/c++11/sstream-inst.o,
  respectively.  No idea where this difference comes from, it might be
  related to the fact that Solaris 11 has COMDAT group support while
  Solaris 10 does not.  I've again decided to live with this difference
  and use the Solaris 10 version of the baselines.

Bootstrapped without regressions on i386-pc-solaris2.1[01] and
sparc-sun-solaris2.1[01], abi_check results are clean with the
additions noted above.

Ok for mainline?
