Enables/Disables Box64's Dynarec building BigBlock.
* 0 : Don't try to build block as big as possible (can help program using lots of thread and a JIT, like C#/Unity) (Default when libmonobdwgc-2.0.so is loaded)
* 1 : Build Dynarec block as big as possible (Default.)
* 2 : Build Dynarec block bigger (don't stop when block overlaps)
* 2 : Build Dynarec block bigger (don't stop when block overlaps, but only for blocks in elf memory)
* 3 : Build Dynarec block bigger (don't stop when block overlaps, for all type of memory)
