[clang] [CIR] Make LLVM & OGCG variables match the same pattern (PR #135427)

To clarify I wasn't saying that the LLVM checks and OGCG checks needed to use the same patterns/names (though it's nice that they do now). The important thing was not to have the value identifiers hard-corded in the checks.

Thanks for the update!
