basicblock hash set vector

[nirizr]

A vector of separate hashes for each basic block, sorted by their value.

This will provide basic-block based matching, while ignoring basic block order changes.

We should have a couple of versions for this, one hashing all data and another hashing only the instruction's opcode.

Fnv, Bernstein will be used for that.

Ready in my own branch, pushed once it's better.
I have a few inheritence problems I need to solve.

Let me know if you'd like me to have a look
