Add crypto_ia32 plugin
Currently this plugin provies AES CBC optimized code. Encryption code supports parallel encryption of 4 buffers with different size and key which improves performance 4x compared to standard serialized aproach. On Skylake Server measured performance is around 0.71 clocks/byte with 256 buffers with size in range between 7000 and 8000 bytes. Measured performance includes overhead of processing crypto ops.
