Inline asm function in loop for AVX2 implementation
...
Right now AVX2 implementation looses to C binding in speed.
This is probably, because of 2 things:
1. Go does not inline `mulBitRightx2` in loop iteration.
2. `minmax` is loaded every time from memory.
In this PR:
1. Unroll `mulBitRightx2` manually and use `mulByteRightx2` instead.
2. Generate `minmax` in place without `LOAD/LEA` instructions.

Add partial AVX2 support (multiplication by 10 and 11)
...
AVX2 permits working with 256-bit registers. Thus we can
multiply 2 GF(2^127) elements in parallel.
This commit adds 2 such functions for multiplication by 10 and 11).
