GNU debug code, replaces standard behavior with debug behavior.
Macros and namespaces used by the implementation outside of debug wrappers to verify certain properties. The __glibcxx_requires_xxx macros are merely wrappers around the __glibcxx_check_xxx wrappers when we are compiling with debug mode, but disappear when we are in release mode so that there is no checking performed in, e.g., the standard library algorithms.
