Summary: Insert warn_unused_result attributes
Product: libc++

OS/Version: Linux

There are many functions in the standard library that should have
warn_unused_result, such as most const member functions (the example that
sparked this bug was c_str() in a void context). Potentially there should be a
macro to disable them on functions where ignoring the return value is not
necessarily a hard bug, as it might be with some C functions that return error
codes.
