The fact that it works only on aligned 32-bit ints is a detail of this
implementation and not a requirement of murmur3 though. AFAICT common
implementations treat this case as an optimization but handle
arbitrarily aligned buffers of arbitrary numbers of bytes, as is the
case for other hashes in my quick survey.

The reference Jenkins hash looks to be the odd one out here in taking
a uint32_t * and a count rather than a char * or void * and a byte
length.
