Bruce Evans 5182dcbec2 Rearrange the inner loop of scanc() to get better code on i*86's 
(on an i486, 10 cycles (+ cache misses) instead of 15).  The
change should be a no-op if the compiler is any good.  The best
possible i*86 code for the same algorithm is only 1 more cycle
faster on i486's so I don't want to bother implementing an
assembler version.

scanc() is a bottleneck for OPOST processing.  It is naturally
about 4 times as slow as bcopy() on 32-bit systems.
