vxworks test cleanups


I'm flushing out a set of vxworks patches, now we're back in stage 1. This first one was developed some time back by Richard Sandiford.

tested on i586-wrs-vxworks, ok?

	gcc/testsuite/
	* lib/target-supports.exp (check_effective_target_vxworks_kernel):
	Fix comment.
	(check_effective_target_vxworks_rtp): New procedure.
	* g++.dg/opt/20050511-1.C: Rename UINT32 for VxWorks kernel mode.
	* g++.dg/warn/miss-format-1.C: XFAIL for VxWorks.
	* g++.old-deja/g++.abi/cxa_vec.C: XFAIL for VxWorks kernels.
	* g++.old-deja/g++.brendan/new3.C: Likewise.
