testsuite: add test coverage for PR analyzer/108045

PR analyzer/108045 reports a leak false positive from -fanalyzer.

The false +ve as reported seems to have been fixed by
r13-6589-g14f5e56a8a766c, but with -fanalyzer-call-summaries there are
two additional false +ves which aren't fixed by that commit.

This patch adds test coverage for these cases.
