ensure no NULL is passed to memcpy 
NULL is valid when size is 0, but memcpy uses nonnull attributes,
so let's not poke the bear

CNv4 JIT compiler for x86-64 and tests 
Minimalistic JIT code generator for random math sequence in CryptonightR.

Usage:
- Allocate writable and executable memory
- Call v4_generate_JIT_code with "buf" pointed to memory allocated on the previous step
- Call the generated code instead of "v4_random_math(code, r)", omit the "code" parameter

discontinue use of alloca 
NetBSD emits:
warning: Warning: reference to the libc supplied alloca(3); this most likely will not work. Please use the compiler provided version of alloca(3), by supplying the appropriate compiler flags (e.g. not -std=c89).

and man 3 alloca says:

       Normally,  gcc(1)  translates  calls  to  alloca()  with  inlined code.  This is not done when either the -ansi, -std=c89, -std=c99, or the
       -std=c11 option is given and the header <alloca.h> is not included.  Otherwise, (without an -ansi or -std=c* option) the glibc  version  of
       <stdlib.h> includes <alloca.h> and that contains the lines:

           #ifdef  __GNUC__
           #define alloca(size)   __builtin_alloca (size)
           #endif

It looks like alloca is a bad idea in modern C/C++, so we use
VLAs for C and std::vector for C++.

c4fbfd786a Small function declaration cleanup in slow-hash.c 
- These functions are declared twice in slow-hash.c. Remove one of the copies.
- The declarations have the wrong return type, should be void, not int.

Function definitions here: 1e74586ee9/src/crypto/aesb.c (L151-L180)
Test plan: make release-test
