generic function

[m4b]

If you like, can merge this and you will be able to test new and old functions side by side.

Additionally, almost everything has been ported to petgraph (except World).

Note:

1. petgraph old function version of ssa_conversion() is broken; i note this in benchmarks, and line numbers. I believe its my dominator implementation
2. you can test new and old via panop cli, using --neo flag for new; it will even run the new rewite_to_ssa (unfortunately, does not seem to be working, as testing on libfoo.so. etc., the function is unfinished
3. We don't have to commit to generic function; its just very easy at the moment to have it generic so can run both side by side.
4. Re generic functions: I have a proposal/idea for this that i think is going to work beautifully, and I think we be best of both worlds, but will require petgraph across the board
5. I believe we want petgraph across the board; as I mentioned in PR, it looks like much of the savings are actually due to switching to petgraph.
6. some functions I added randomly, etc., don't consider Fun the final say, etc. We can remove anything you don't like, etc.

Some numbers, specifically testing the effect of porting the Program cfg to petgraph:

libc, f2d92e1 and ae19d49, 2999 functions:

function lib	program lib	neo func	time	RES memory
petgraph	panopticon	yes	0:07.14	499440 KB
petgraph	panopticon	no	0:06.00	1822716 KB
petgraph	petgraph	yes	0:06.13	494684 KB
petgraph	petgraph	no	0:04.75	1818756 KB

Lets call it a time memory trade off 😹
