[testsuite] Several Tru64 UNIX testsuite fixes

[Rainer Orth <ro at CeBiTec dot Uni-Bielefeld dot DE>]

This patch fixes a couple of pretty obvious testsuite failures on Tru64 UNIX:

FAIL: g++.dg/cpp/_Pragma1.C (test for excess errors)

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/cpp/_Pragma1.C:9:10: warning: #pragma pack(push[, id], <n>) is not supported on this target
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/cpp/_Pragma1.C:11:17: warning: #pragma pack(pop[, id], <n>) is not supported on this target

Skip since the target doesn't support #pragma pack(push/pop).

FAIL: g++.dg/eh/spbp.C (test for excess errors)
WARNING: g++.dg/eh/spbp.C compilation failed to produce executable

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/eh/spbp.C:1:0: error: target system does not support the "dwarf-2" debug format

Skip since this isn't a DWARF-2 target.  For the future, it seems better
to introduce a new effective-target keyword to handle cases like this
once and for all instead of requiring maintainers of non-DWARF-2-targets
to skip the testcases individually.

FAIL: g++.dg/ext/label13.C (test for excess errors)
WARNING: g++.dg/ext/label13.C compilation failed to produce executable

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/ext/label13.C:11:1: sorry, unimplemented: function 'C::C()' can never be copied because it saves address of local label in a static variable

This seems to be the same issue as on Darwin, so XFAIL.

FAIL: g++.dg/other/pragma-ep-1.C (test for excess errors)

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/other/pragma-ep-1.C:26:12: warning: ISO C++ forbids casting between pointer-to-function and pointer-to-object
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/other/pragma-ep-1.C:26:26: warning: ISO C++ forbids casting between pointer-to-function and pointer-to-object
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/other/pragma-ep-1.C:26:40: warning: ISO C++ forbids casting between pointer-to-function and pointer-to-object
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/other/pragma-ep-1.C:26:56: warning: ISO C++ forbids casting between pointer-to-function and pointer-to-object

I had already submitted a patch years ago, but it has never been reviewed:

	4.1 PATCH: Fix Tru64 UNIX #pragma extern_prefix testcase
	http://gcc.gnu.org/ml/gcc-patches/2005-08/msg00603.html

FAIL: gcc.dg/mtune.c  (test for errors, line )
FAIL: gcc.dg/mtune.c (test for excess errors)

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/mtune.c:1:0: error: bad value 'foo' for -mcpu switch

Just add another dg-bogus for -mcpu.

FAIL: objc.dg/dwarf-1.m (test for excess errors)
ERROR: objc.dg/dwarf-1.m: error executing dg-final: couldn't open "dwarf-1.s": no such file or directory
UNRESOLVED: objc.dg/dwarf-1.m: error executing dg-final: couldn't open "dwarf-1.s": no such file or directory

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/objc.dg/dwarf-1.m:1:0: error: target system does not support the "dwarf-2" debug format

XFAIL again, just like objc.dg/dwarf-2.m.

Ok for mainline before the release?  (I will be away from my mail during
the easter weekend, only returning next tuesday.)
