98cbb217ac mem -> reg & reg->reg moves take the same time; so save a cycle by reading 
the block length from the stack instead of caching it in a register.

479a1c33c9 Provide i386 versions of div and ldiv -- they are simpler than the C versions, 
since the idiv instruction does the right thing wrt truncating towards zero.

e09d2f42db Use "testb %cl,%cl" instead of "cmpb $0,%cl". 
This saves three cycles per character, and reduces the size of the
function by eight bytes (the loop is unrolled eight times).
Thanks to davidg for pointing this out.

b3f9f8f6f4 Provide an assembly language version of labs(). 
Since ints and longs are both 32 bits on a i386, we could alias abs()
and labs() together as mycroft did with memmove()/memcpy(), but I'm
waiting on an interpretation ruling to see if it is legal.
