/* Use the multiplicative method, as described in Knuth 6.4, to obtain
a hash code for P in the range [0, MAX). MAX == 2^LOGMAX.
Summary of this method: Multiply p by some number A that's
relatively prime to 2^sizeof(size_t). The result is two words.
Discard the most significant word, and return the most significant
N bits of the least significant word. As suggested by Knuth, our
choice for A is the integer part of (ULONG_MAX + 1.0) / phi, where phi
is the golden ratio.
We don't need to do anything special for full-width multiplication
because we're only interested in the least significant word of the
product, and unsigned arithmetic in C is modulo the word size. */
