    testsuite: add various -Wanalyzer-null-dereference false +ve test cases

    There are various -Wanalyzer-null-dereference false +ves in bugzilla
    that I've been attempting to fix.  Unfortunately I haven't made much
    progress, but it seems worth at least capturing the reduced
    reproducers as test cases, to make it easier to spot changes in
    behavior.
