99a3c3ff - [InstCombine][GitHub] Auto-add llvm:instcombine label (NFC) (#115736)

[InstCombine][GitHub] Auto-add llvm:instcombine label (NFC) (#115736) Add `llvm:instcombine` label to PRs touching InstCombine or InstSimplify. (We track InstSimplify issues under `llvm:instcombine` as well, so I added it here as well.)
