This commit adds a new C++ test case to the GCC testsuite. The testcase is designed to expose a regression related to Pointer Analysis (PTA) and function return values, specifically involving __builtin_memcpy and conditional memory allocation.
This regression was introduced by a previous fix for PR tree-optimization/112653 and affects multiple GCC branches. The new test ensures this specific scenario is covered and verified.
