...r symbols they reference to become
available (as our internal representation, Core, allows references
in any order without forward declarations). This theoretically
offers a performance improvement and somewhat simplifies the code
generator. Here we emit aliases like,
@SWn_srt$alias = alias private i8* bitcast (%SWn_srt_struct* @SWn_srt to i8*)
again, using the `$alias` in all references,
Unfortunately, recent LLVMs reject both of these uses. The first is
rejected as aliases can no longer reference items other than
definitions, e.g.
opt: hi.ll:414:36: error:...
