Ohadn/blake2s last block opcode vm

[ohad-nir-starkware]

Blake2sLastBlock opcode runner

Description

Adding the opcode Blake2sLastBlock to the VM.
Expects op0 to be a pointer to a sequence of 9 felts and and op1 to be a pointer to a sequence of 16 felts.
Said felts should represent u32 integers, i.e. have value of at most 2**32-1.
The first 8 felts of op0 represent a state, the 9th represents the counter and the 10th represents counter+n_bytes i.e. the total length of the entire message.
The 16 felts of op1 represent a message.
The "output" consists of 8 felts representing u32 numbers of the Blake2s compression of the last block.
dst should be a pointer, it points to a sequence of 8 cells which each should either be uninitialised or already contain a value matching that of the output at the same index.
The opcode inserts the aforementioned output into the 8 cells [dst], [dst+1], ... [dst+7] (and yields an error if one of said cells already contains a value differing from the output).

Currently Blake2sLastBlock has opcode_num 16, meaning encoded_instr is expanded to 128 bits with the 63 most significant bits expected to be 0 (otherwise yield an error).

The motivation is that it has been decided at Starkware that Blake2sLastBlock is to be implemented at an opcode, thus it needs to be supported by the runner.
