Hello.

Many significant changes has landed in mainline and will be released as GCC 8.1.
I decided to use various GCC configs we have and test how there configuration differ
in size and also binary size.

This is first part where I measured binary size, speed comparison will follow.
Configuration names should be self-explaining, the 'system-*' is built done
without bootstrap with my system compiler (GCC 7.3.0). All builds are done
on my Intel Haswell machine.

Feel free to reply if you need any explanation.
Martin
