Missing opcode: Implement BreakPoint() and Fatal()

[avdgrinten]

Add the missing opcode and a unit test.

How should we handle a breakpoint?
I was thinking of creating a laihost_function which will get all the relevant data (Table it occurred in, PC) and give the host a choice of returning or not.

Does AML on real hardware even use BreakPoint()? If no, why bother with it?

[thomtl]

Its not exactly a very complicated opcode (just itself) and it would be nice to just have it. Also some people might run on Engineering bioses that might have them

[avdgrinten]

IMHO we can just warn and ignore BreakPoint().

[thomtl]

Alright, i'll have breakpoint up shortly, but fatal has termargs so imma figure that whole thing out

[avdgrinten]

Why do you skip 2 bytes after the breakpoint opcode? Did you add a unit test for this?

[avdgrinten]

Fatal() can probably be handled as the other AML operators (e.g., Add()).

[thomtl]

I did actually create a unit test, but im dumb, i'll fix it and push the unit test in a moment.
