These aren't too related to this problem, there is barely any discussion
about performance, its mostly about support.

I would use rule that if user doesn't care about performance by using
obsolete gcc that generates slower code why should we care?

Also as I said before removing many of these would improve performance
as they are obsolete and libcall is faster.
