bloodborne-recomp: statically recompiling Bloodborne

This static recompiler reads Bloodborne for the PlayStation 4, CUSA03173 update 1.09, and writes its functions as C. The project page counts 181,521 of 181,570 functions recompiled and 10,284,725 of 10,691,122 instructions. The player's launcher builds that library on the player's own device. Code that is not recompiled yet still runs in the bbcpu translator.
