replacements for fprintf() integer to string...
* final.c, output.h (fprint_whex, fprint_w, fprint_ul, sprint_ul):
New functions serving as fast replacements for fprintf() integer
to string conversions. They were used in the following changes.
* final.c (sprint_ul_rev): Internal helper for the above.
