GCC 5 is the current stable release and, normally, only bugfixes are added to it. If you wish to propose a backport, you'll need to write to the release managers (for example, by writing to gcc@) and ask for permission, then you need to do (or find someone to do) the backport, test it and commit it. I'd rather have two new features in GCC 6 than one new feature in both GCC 5 and GCC 6, thus I (and likely others) prefer to dedicate my time to fixing other things (and there is a lot of work to do: https://gcc.gnu.org/wiki/GettingStarted#Basics:_Contributing_to_GCC_in_10_easy_steps) rather than on back-porting new features.
