This commit adds a new test case to the GCC testsuite to verify that a recently-introduced fix to the static analyzer is working correctly. The test is based on a reduced version of libstdc++ code, focusing on the small string optimization of std::string. The original bug caused the analyzer to report false positives due to confusion between small-string-optimization and heap allocation branches.
