Modified Files:
        src/usr.bin/cmp: regular.c

Log Message:
Make cmp -s and cmp -l much faster by comparing blocks and skipping any
line number calculations not needed.  Approx 3-4x faster for two multi-GB
in-cache files on my Zen 3.

Restores the spirit of a NetII optimisation lost with 4.4lite2 import
in 1995.
