Optimized dataset read (#211) 
* Optimized dataset read

There was a false dependency on readReg2 and readReg3 (caused by `xor rbp, rax` instruction) when reading dataset item (see design.md - 4.6.2 Loop execution, steps 5 and 7). This change uses `ma` register to read dataset item before the whole `rbp` (`ma` and `mx`) is changed, so superscalar and out-of-order CPU can start executing it earlier.

Results: https://i.imgur.com/Bpeq9mx.png

~1% speedup on modern Intel/AMD CPUs.

* ARMv8: optimized dataset read

Break dependency from readReg2 and readReg3.

* Fixed light mode hashing

Fix compilation and JIT support on NetBSD

1. Disable hugepages (not supported).
2. Force W^X (required).
3. When allocating JIT memory, PROT_EXEC must be reserved
   in order to set the pages executable later.

SChernykh 219c02e1e5 Combined hash and fill AES loop (#166) 
Adds more parallelizm into AES loop so modern CPUs can take advantage of it. Also, scratchpad data moves between L1 and L3 caches only one time which saves time and energy per hash.
