visibility-[1-9a].c: Change to use scan-hidden instead of scan-assembler.

2004-10-28  Andrew Pinski  <pinskia@physics.uc.edu>

        * gcc.dg/visibility-[1-9a].c: Change to use scan-hidden instead of
        scan-assembler.
        * lib/scanasm.exp (hidden-scan-for): New proc.
        (scan-hidden): Use hidden-scan-for instead of constructing the scan
        string.
        (scan-not-hidden): Likewise.
        * lib/target-supports.exp (check_visibility_available): mach-o is
        support too.
