re PR testsuite/19231 (Execute failure in gcc.c-torture/execute/builtins/strlen-3.c with -fpic/-fPIC)

	* g++.dg/opt/range-test-1.C: Prevent re-inclusion of system
	headers.
	* g++.old-deja/g++.law/profile1.C: No longer expect fail on OSR5.
	* gcc.c-torture/compile/20000804-1.c: Skip if using -fPIC on X86.
	* gcc.target/i386/asm-3.c: Ditto.
	* gcc.target/i386/clobbers.c: Ditto.
	* gcc.dg/tree-ssa/ssa-dce-2.c: Make t() static and prototype it.
	* gcc.target/i386/cmov1.c: Make magic* static so it matches the
	test regexp.
	* gcc.target/i386/mul.c: Ditto.
	* gcc.target/i386/ssetype-1.c: Ditto.
	* gcc.dg/20040813-1.c: Skip on SVR5 systems.
	* gcc.c-torture/execute/builtins/strlen-3.c: Declare variables as
	static so the test works with -fPIC mode too. Based on comment in
	PR19231 by Pinski.
	* gcc.dg/nest.c: No longer fail on SCO systems as it has -pg again.
