9d38ffd9f1 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.

2ec1d9ca61 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.

98484742cc 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.

e89635ef9e 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).

e50ba7b643 Fix DIV and DIVU with negative numbers. 
Math.floor does the wrong thing (should round to zero). `>> 0` has the correct behaviour.

fc5d8e9b65 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.

4effd2747b Fix precision errors in multiplication instructions. 
For large 32 bit values this can overflow precision of a Number.

This fixes Mario getting stuck on the stairs in the castle.
