----------------------------------------------------------------------------------------------------------------
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
