Xiangling_L planned changes to this revision.

Importantly, this patch provides context and shows where things are going of static init of AIX in LLVM. And hope it would help reviewers with its parent patch:  D74015 <https://reviews.llvm.org/D74015>.

- Provides no piroirity supoort && disables/ignores three priority related attributes: init_priority, ctor attr, dtor attr;
  - '-qunique' in XLC compiler equivalent behavior of emitting sinit and sterm functions name using `getUniqueModuleId()` function in LLVM;
  - Add a simple testcase to emit IR sample with sinit80000000, srterm, and sterm80000000
