620b8da57f Fix y-res scaling hack. 
I'm not 100% sure about this but it seems more likely to be based on whether the screen is interlaced than the screen width.

f7014c4b02 Tidy vi width/height calculation and use for raw framebuffer code. 
There are still a number of TODOs, like figuring out why the hacky 240/237 constant is needed.

05020bf891 Clear the CAUSE_IP3 bit when the MI interrupt mask is cleared. 
This gets https://github.com/PeterLemon/N64/blob/master/CPUTest/Exceptions/VIIntr/ExceptionVIIntrDisabled.asm passing.

356f0a9004 Overhaul VI interrupts. 
* Increment CURRENT based on number of executed instructions
* Set interrupt based on cart country / tv type
* Handle interlaced modes

This fixes a bunch of roms (boot issues and timing issues).

c6da98abd0 Fix DIV and DIVU with negative numbers. 
Math.floor does the wrong thing (should round to zero). `>> 0` has the correct behaviour.

c4f105446d Rewrite DDIV and DDIVU to use BigInt. 
This is probably slower than doing 64+32 bit paths, but it's not a common operator and on modern computers should be negligible. It's also much more likely to be correct.

7bff96d4ab Fix precision errors in multiplication instructions.
