SChernykh 166e0d80f5 Fixed cache->jit memory leak 
1. `cache->jit = new randomx::JitCompiler();` - succeeds
2. `cache->memory = (uint8_t*)randomx::LargePageAllocator::allocMemory(randomx::CacheSize);` - fails
3. `if (cache && cache->memory == nullptr) randomx_release_cache(cache);` is executed
4. randomx_release_cache checks `if (cache->memory != nullptr)` and does nothing
5. cache->jit stays allocated

tevador 905ee34f8b Do not use reserved identifiers in intrin_portable.h 
Identifiers starting with an underscore followed by an uppercase
letter are reserved for the compiler.

SChernykh bbc9ccc90b Fixed a crash in MSVC Debug and RelWithDebInfo builds 
MSVC debug/relwithdebinfo builds use jmp trampolines for ASM functions, so these must be traversed to get the actual address of the code for each function.

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.

Vladimir 01914b49cd Fixes for cmake build with visual studio (#144) 
* Fixed CMake configuration for visual studio build

Added proper asm source and set correct type.

* Disabled stadard layout check of randomx_cache for visual studio debug

Required to silence static_assert which fails on Visual Studio Debug
configuation.

* Fixed warning message and defines check

* Removed unsupported flags for MSVC compiler

* Enabled AVX2 for msvc

* Fixed formatting in CmakeLists

* Added generation of configuration.asm by CMake for MSVC
