Make two texts static in ReplayInlineAdvisor

This commit makes two variables static.
That makes two buildbot tests pass with short string annotations.

Short string annotations PR (reverted):
- llvm#79049

Tests fixed with this PR:
``
  LLVM :: Transforms/Inline/cgscc-inline-replay.ll
  LLVM :: Transforms/SampleProfile/inline-replay.ll
```
Buildbot output: https://lab.llvm.org/buildbot/#/builders/5/builds/40364/steps/9/logs/stdio

This PR does not resolve a problem with `Clang :: SemaCXX/builtins.cpp`.

I suspect that there may be use after end of life bug and it's fixed by this change.
