A 2013 paper [1] proposed 5 simple tests for evaluating the effectiveness of static analysis tools at detecting CWE-121 ("Stack-based Buffer Overflow"). The tests can be found in: https://samate.nist.gov/SARD/test-suites/81 This patch adds theses 5 tests to -fanalyzer's testsuite, lightly modified to add DejaGnu directives. This is for unit-testing; for broader testing of -fanalyzer I'm working on a separate integration testing suite that builds various real-world C projects with -fanalyzer, currently here: https://github.com/davidmalcolm/gcc-analyzer-integration-tests Successfully regrtested on x86_64-pc-linux-gnu.
