e290fb8f79 Changed beq's to jeq's, because (a) the jeq gets optimized to a short branch, 
and (b) gas currently assembles the beq's wrongly.

32d96ccd3c Remove special case for len == 0 --- It wasn't needed. By dropping the 
conditional, the general case (where we are actually swapping bytes) is
a tiny bit faster.

823c36577c Change instances of LIBC_RCS back to LIBC_SCCS. If we are going to change 
th LIBC_RCS, the entire source tree should be updated at once.
Remove && !defined(lint) from conditionals around rcs id's.  No one is
ever going to pass a *.s file through lint.

78942d40e6 First cut; not sure if it's right. Very like it is, because it's

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.
