M1 10x faster than Intel at integral division, throughput one 64-bit divide in two cycles

[Manu]

It's a strange thing to optimise... I seem to do an integer divide so
infrequently, that I can't imagine a measurable improvement in most code
I've ever written if it were substantially faster. I feel like I stopped
doing frequent integer divides right about the same time computers got
FPU's...
