    testsuite: Silence analyzer/pr51628-30.c for default_packed
    
    On default_packed targets like PRU, a warning in the file included from
    analyzer/pr51628-30.c is reported as spurious one, even though it has been
    annotated there:
    
      Excess errors:
      gcc/gcc/testsuite/gcc.dg/analyzer/torture/../../../c-c++-common/pr51628-30.c:7:19: warning: 'packed' attribute ignored for field of type 'struct B' [-Wattributes]
    
    Mark that gcc.dg/analyzer/torture/pr51628-30.c generates excess warnings
    for default_packed targets.  This is safe because the original test case
    covered an ICE, not a diagnostic error.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/analyzer/torture/pr51628-30.c: Test can spill excess
            errors for default_packed targets.
