Fix: hardcoded JIT code buffer size (#98) 
* code buffer size is calculated based on RandomX parameters
* added a maximum value constraint for program size and superscalar latency
* reduced the x86 code size of memory instructions by 1 byte
* disclaimer note in configuration documentation

Refactoring (#95) 
* Blake2Generator::getInt32 renamed to getUInt32 to avoid confusion
* isPowerOf2 renamed to isZeroOrPowerOf2 to avoid confusion
* added asserts to validate the input/output size of AES functions
* fixed possible overflow in JitCompilerX86::getCodeSize (unused function)

Decrease the frequency of FADD/FSUB in favor of FMUL (#77) 
* this better matches CPU capabilities since execution ports are usually split 1:1 between fadd and fmul
* the frequency of FSWAP_R decreased from 8 to 4 (it's ASIC-friendly)
* activate IROL_R instruction

* instruction decode/execute separated into class BytecodeMachine
* added randomx-tests project
* removed the use of non-portable __COUNTER__ macro
* removed the use of unsupported FENV_ACCESS pragma
