[testsuite] Adjust recent g++.dg/tls/thread_local testcases

[Eric Botcazou]

5 of them fail on Solaris 9 and 10 because they require __cxa_atexit to pass.  
And 4 others fail on Solaris 9 only because of a TLS initialization failure.

Adjusted thus, tested on SPARC/Solaris 9, SPARC/Solaris 10 and x86-64/Linux, 
applied on the mainline.

        * g++.dg/tls/thread_local-order1.C: Add dg-require-cxa-atexit.
        * g++.dg/tls/thread_local3g.C: Likewise.
        * g++.dg/tls/thread_local4g.C: Likewise.
        * g++.dg/tls/thread_local5g.C: Likewise.
        * g++.dg/tls/thread_local6g.C: Likewise.
        * g++.dg/tls/thread_local-cse.C: XFAIL on Solaris 9.
        * g++.dg/tls/thread_local2.C: Likewise.
        * g++.dg/tls/thread_local2g.C: Likewise.
        * g++.dg/tls/thread_local6.C: Likewise.
