[tree-ssa] tree-ssa/20030730-{1,2}.c fixes

[law@redhat.com]

These tests weren't running.  Apparently unit-at-a-time compilation
determined that it was uninteresting to compile the "foo" function in
both tests :-)

Instead of getting an error, they pass now :-)



	* gcc.dg/tree-ssa/20030730-1.c: Make "foo" have external linkage.
	* gcc.dg/tree-ssa/20030730-2.c: Similarly.
