The only reason I thought was the pass would iterate through all atoms 
compared to the ELF Layout only looking at atoms that belong to the 
sections .init_array/.fini_array.

Additionally do all the ELF subtargets treat the init_array by priority 
? the ELF ABI document seems to be outdated on this.

Was looking at this bug, and it looks like Linker supports sorting 
.ctors.NNNN too, not sure if its still relavant ? Any ideas ?
