Copied from gcc/hashtable.c. Zack had the following to say with respect
to applicability, though note that unlike hashtable.c, this hash table
implementation re-hashes rather than chain buckets.

I got it by extracting all the identifiers from all the source code
I had lying around in mid-1999, and testing many recurrences of
the form "H_n = H_{n-1} * K + c_n * L + M" where K, L, M were either
prime numbers or the appropriate identity. This was the best one.
I don't remember exactly what constituted "best", except I was
looking at bucket-length distributions mostly.
So it should be very good at hashing identifiers, but might not be
as good at arbitrary strings.
I'll add that it thoroughly trounces the hash functions recommended
for this use at http://burtleburtle.net/bob/hash/index.html, both
on speed and bucket distribution. I haven't tried it against the
function they just started using for Perl's hashes. */
