[testsuite] XFAIL g++.dg/debug/dwarf2/nested-4.C on Solaris with Sun as

[Rainer Orth]

Once COMDAT group support on Solaris 11+ with Sun as got re-enabled

        https://gcc.gnu.org/ml/gcc-patches/2014-08/msg01120.html

g++.dg/debug/dwarf2/nested-4.C is FAILing in that configuration:

FAIL: g++.dg/debug/dwarf2/nested-4.C  -std=gnu++98  scan-assembler-times 
debug_types 2
FAIL: g++.dg/debug/dwarf2/nested-4.C  -std=gnu++11  scan-assembler-times 
debug_types 2
FAIL: g++.dg/debug/dwarf2/nested-4.C  -std=gnu++1y  scan-assembler-times 
debug_types 2

We have this in various configurations:

* without COMDAT group:

        .section        .debug_types,"",@progbits
        .section        .debug_types,"",@progbits

* with COMDAT group with as:

        .section        .debug_types%wt.4e05dcd4da926741,"",@progbits
        .group  wt.4e05dcd4da926741,.debug_types%wt.4e05dcd4da926741,#comdat
        .section        .debug_types%wt.b606c86c38313abe,"",@progbits
        .group  wt.b606c86c38313abe,.debug_types%wt.b606c86c38313abe,#comdat
        .section        .debug_types%wt.b606c86c38313abe,"",@progbits
        .section        .debug_types%wt.4e05dcd4da926741,"",@progbits

* with COMDAT group with gas:

        .section        .debug_types,"G",@progbits,wt.4e05dcd4da926741,comdat
        .section        .debug_types,"G",@progbits,wt.b606c86c38313abe,comdat

Given that the last two .debug_types%wt.* sections in the COMDAT/as
config (which are empty) seem like an implementation artefact, it seems
best to just XFAIL the test in that configuration rather than handling
this quirk.

Tested with the appropriate runtest invocation on i386-pc-solaris2.11,
sparc-sun-solaris2.11, and x86_64-unknown-linux-gnu.

Ok for mainline?
