[VxWorks] Various testsuite patches

[Richard Sandiford <richard at codesourcery dot com>]

This patch fixes a few spurious failures in the test results for
i586-wrs-vxworks.  Specifically:

- The VxWorks port doesn't support profiilng.  From config/vx-common.h:

    #define VXWORKS_FUNCTION_PROFILER(FILE, LABELNO) do	\
    {							\
      sorry ("profiler support for VxWorks");		\
    } while (0)

- VxWorks doesn't support stabs.

- VxWorks doesn't have a full C99 runtime.

- VxWorks doesn't have inttypes.h.

- vxworks/initpri2.c is specifically for kernel mode.  I've added a new
  effective-target procedure to test for that.

Tested on i586-wrs-vxworks.  OK to install?

gcc/testsuite/
	* lib/target-supports.exp (check_profiling_available): Return false
	for VxWorks.
	(check_effective_target_vxworks_kernel): New procedure.
	* gcc.dg/20040813-1.c: Extend list of stabless targets to include
	VxWorks.
	* gcc.dg/builtins-config.h: Do not define HAVE_C99_RUNTIME on VxWorks.
	* gcc.dg/intmax_t-1.c: Extend list of targets with inttypes.h to
	include VxWorks.
	* gcc.dg/vxworks/initpri2.c: Require vxworks_kernel.
