The IA-64 visibility-1.c testcase has a static variable that is read but
not written.  New optimization support is able to optimize away the
variable causing the testcase to fail.  This just changes the testcase
to write to variables instead of reading from them.

This was tested with a C only make check to verify that it works, and
then was checked in.
