     The format of Frida's ASAN is signficantly different from LLVM ASAN. 
     
     In Frida ASAN, we attempt to find the lowest possible bit such that there is no mapping with that bit. That is to say, for some bit x, there is no mapping greater than

+    
     The reasoning for this is that new pages are zeroed, so, by default, every qword is poisoned and we must explicitly unpoison any byte. 
 
     Much like LLVM ASAN, shadow bytes are qword based. This is to say that each shadow byte maps to one qword. The shadow calculation is as follows:
