Techjar 8cfe49295f VideoCommon: Add fallback handling for bounding box when disabled or unsupported 
The SDK seems to write "default" bounding box values before every draw
(1023 0 1023 0 are the only values encountered so far, which happen to
be the extents allowed by the BP registers) to reset the registers for
comparison in the pixel engine, and presumably to detect whether GX has
updated the registers with real values. Handling these writes and
returning them on read when bounding box emulation is disabled or
unsupported, even without computing real values from rendering, seems
to prevent games from corrupting memory or crashing.

This obviously does not fix any effects that rely on bounding box
emulation, but having the game not clobber its own code/data or just
outright crash is a definite improvement.

Purpose: Writes to the BP registers
Called: At the end of every: OpcodeDecoding.cpp ExecuteDisplayList > Decode() > LoadBPReg
How It Works: First the pipeline is flushed then update the bpmem with the new value.
Some of the BP cases have to call certain functions while others just update the bpmem.
some bp cases check the changes variable, because they might not have to be updated all
the time
NOTE: it seems not all bp cases like checking changes, so calling if (bp.changes == 0 ? false :
true)
had to be ditched and the games seem to work fine with out it.
NOTE2: Yet Another GameCube Documentation calls them Bypass Raster State Registers but possibly
completely wrong
NOTE3: This controls the register groups: RAS1/2, SU, TF, TEV, C/Z, PEC
TODO: Turn into function table. The (future) DisplayList (DL) jit can then call the functions
directly,
getting rid of dynamic dispatch. Unfortunately, few games use DLs properly - most\
just stuff geometry in them and don't put state changes there
