FNV-1a with the t ^= 2 * t mangling running my new testsuite on either PR 9471 
or PR 9534 using the 64-bit FNV multiplier to produce 64-bit hashes. In other 
words, the code from PR 9534 but just changing the multiplier.

On the full 64-bit range, I got 2 collisions (where statistically 0 would be 
expected). When truncated to 32-bits, I got about 1700 collisions (where 
statistically about 15 would be expected).
