Refactoring (#95)

Browse Source 
* 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)
