I took a look at `isSupportedByOpenMPIRBuilder()` and seems like it is more suitable for a check against work-sharing loop construct, not for `simd`.  

And for `simd`, I am not sure what features I should be checking for.  One check I can think of is checking whether any of the not-yet-supported clauses is present in the simd directive or not.  Am I on the right track?

+        // Emit the associated statement and get its loop representation.
+        auto DL = SourceLocToDebugLoc(S.getBeginLoc());
+        const Stmt *Inner = S.getRawStmt();

I am inspired by [[ https://github.com/llvm/llvm-project/blob/003c9c7457d08888be5deeca7eee84ab5f110bf6/clang/lib/CodeGen/CGStmtOpenMP.cpp#L2611 | existing code ]] though
