bug#23712: [PATCH 1/6] maint: mark a couple of static variables const

[Paul Eggert]

Thanks, this patch was installed into grep in June so I'm marking the bug report 
as done.

Also, I installed the attached two patches as followup. The first is because 
I've run into too many compilers that complain about 'static const int x;' on 
the grounds that x should have an initializer. Rewriting the code to avoid these 
zero constants makes the code a tiny bit smaller on x86-64, so it's likely a 
tiny win anyway.

The 2nd patch changes this code to use 64-bit words on x86-64 GNU/Linux, much as 
other parts of grep already do. This makes the code a tiny bit smaller too.

The runtime performance change is likely so small I haven't bothered to try to 
measure it. Perhaps some day compilers will be smart enough to put those 256-bit 
arrays into registers and regex nerds can tune it some more....
