This commit adjusts GCC’s test suite for C++ coroutines by disabling the ‘-Winvalid-specialization’ warning flag for specific test cases. These tests define specializations for std::coroutine_handle, which have been marked with [[_Clang::__no_specializations]] in recent revisions, causing the warning to be incorrectly triggered.
