We have HIP apps which ship bitcode library which may contain
llvm.compiler.used or llvm.global_ctors which use addr space 0. If we switch to
use addr space 1, the new HIP app may not be able to link with the existing
bitcode libraries.
My understanding is that the addr space used in llvm.compiler.used or
llvm.global_ctors do not really have meanings since no one loads or stores to
them. As long as they are the same for different TU's it is fine. It should be
OK to use addr space 0.
