This improves gcd performance by about 300%
I assume this patch is still valid, if not I could come up with a new one.

I think embedding of Rational already made same result. It internally uses long type of C for Fixnums.
This patch may be still meaningful for 1.8. But extension of Fixnum needs discussion.
