[testsuite] More Tru64 UNIX V5.1 testsuite fixes

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

This patch fixes a couple of additional Tru64 UNIX V5.1 testsuite
failures:

FAIL: g++.dg/cdce3.C (test for excess errors)
WARNING: g++.dg/cdce3.C compilation failed to produce executable
FAIL: g++.dg/cdce3.C scan-tree-dump cdce "cdce3.C:95: note: function
call is shrink-wrapped into error conditions.": dump file does not exist
[...]

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/cdce3.C:74:1: error: 'exp2f' was not declared in this scope
[...]

While Tru64 UNIX V5.1 has a fairly complete C99 runtime, the exp2*
functions are missing, thus skip the testcase to avoid the `compilation
failed' and `dump file does not exist' warnings.

FAIL: g++.dg/warn/miss-format-1.C scanf attribute warning (test for warnings, line 26)
FAIL: g++.dg/warn/miss-format-1.C (test for excess errors)

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/warn/miss-format-1.C:26:18: error: 'vscanf' was not declared in this scope

XFAIL as on other platforms without vscanf.

FAIL: gcc.c-torture/compile/limits-declparen.c  -O3 -g  (test for excess errors)
Excess errors:
mips-tfile, /tmp//cceinZCT.s:33 string too big (58957 bytes)

Excess errors:
mips-tfile, /tmp//cceinZCT.s:33 string too big (58957 bytes)
line:	 #.stabs	"q4_var:G16=*17=*18=*19=*20=*21=*22=*23=*24=*25=*26=*27
[...]

This is an inherent limitation of the current implementation of
mips-tfile, which limits strings to the pagesize.  I'll try to get gas
working to avoid that ugly hack, until then XFAIL.

FAIL: gcc.dg/c99-tgmath-1.c (test for excess errors)
FAIL: gcc.dg/c99-tgmath-2.c (test for excess errors)
ERROR: gcc.dg/c99-tgmath-2.c: error executing dg-final: couldn't open "c99-tgmath-2.s": no such file or directory
UNRESOLVED: gcc.dg/c99-tgmath-2.c: error executing dg-final: couldn't open "c99-tgmath-2.s": no such file or directory

Excess errors:
In file included from /vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/c99-tgmath-1.c:8:0:
/vol/gcc/obj/regression/trunk/5.1b-gcc/build/gcc/include/tgmath.h:35:21: fatal error: complex.h: No such file or directory
compilation terminated.

Again, the C99 runtime is incomplete and lacks <complex.h> completely,
thus skip to avoid the dg-final errors.

Bootstrapped without regressions on alpha-dec-osf5.1b.

Ok for mainline and 4.5 branch?
