5f0f2506e8 soft_aes: fix previous optimization 
Previously removed unrolled variant is faster on some CPUs
Some CPUs are faster with added unrolled variant
The best variant depends on number of threads on some CPUs

a84b45b1bb RandomX: added parameter for scratchpad prefetch mode 
`scratchpad_prefetch_mode` can have 4 values:
0: off
1: use `prefetcht0` instruction (default, same as previous XMRig versions)
2: use `prefetchnta` instruction (faster on Coffee Lake and a few other CPUs)
3: use `mov` instruction

b665d2d865 Adopt new SSE2NEON and reduce ARM-specific changes 
This patch updated SSE2NEON [1], which contains more functions
provided by Intel intrinsics, only implemented with NEON-based
counterparts to produce the exact semantics of the intrinsics.
Consequently, ARM-specific changes against CryptoNight_arm can
be reduced as well.
