Paul Brook d1da229ff1 i386: pcmpestr 64-bit sign extension bug 
The abs1 function in ops_sse.h only works sorrectly when the result fits
in a signed int. This is fine most of the time because we're only dealing
with byte sized values.

However pcmp_elen helper function uses abs1 to calculate the absolute value
of a cpu register. This incorrectly truncates to 32 bits, and will give
the wrong anser for the most negative value.

Fix by open coding the saturation check before taking the absolute value.
