This macro binds the SSBO Info Buffer as the current ConstBuffer.
This buffer is usually bound to c0 during shader execution.
Games seem to use this macro instead of directly writing the address for some reason.
Writing to this method will cause the written value to be stored in the currently-set ConstBuffer plus CB_POS.
This method is usually used to upload uniforms or other shader-visible data.
It'll now set the CB_SIZE, CB_ADDRESS and CB_BIND registers when it's called.
Presumably this SetShader function is binding the constant shader uniforms to buffer 1 (c1[]).
Register 0xE24 is actually a macro that sets some shader parameters in the register structure.
Macros are uploaded to the GPU at startup and have their own ISA, we'll probably write an interpreter for this in the future.
