This reverts commit 3c161467f0.
Reason for revert: need to keep iOS simulator (Build-Mac-Clang-x64-Release-iOS) in mind
Original change's description:
> restore murmur3 for older iOS devices
>
> For reference, the relative costs are roughly,
> - our hash with CRC32c instructions 1x
> - Murmur3 11x
> - our hash with CRC32c fallback 23x
>
> So this should be a ~2x speedup for those
> older iOS devices not using an arm64e slice.
