Hi,

These are a series of patches to improve the performance of dfa.  We can
speed-up dfa by improving memory accessibility etc.  The following is the
case that is particularly effective.

$ ( seq 100000 | sed 's/$/  abcdefg hijklmn opqrstu vwxyz/'; echo XXXXXX. ) >in

(Before)
$ time -p env LC_ALL=C src/grep -vf in in
real 39.20
user 20.35
sys 18.78

(After)
$ time -p env LC_ALL=C src/grep -vf in in
real 6.87
user 6.38
sys 0.48

Thanks,
Norihiro
