Fold multiple asm statements into one so that the compiler at a certain
optimization level (-march=pentium-mmx for example) does not insert intermediate ops which would trash the carry. Change both sys/i386/i386/in_cksum.c[1] and sys/i386/include/in_cksum.h. To my best understanding the same problem was addressed in rev. 1.16 of src/sys/i386/include/in_cksum.h for just a single function 3y ago.
