[PATCH] D90324: [Flang][OpenMP][NFC][1/2] Reorder OmpStructureChecker and simplify it.

[Kiran Chandramohan via Phabricator via llvm-commits]

> Makes seperation between constructs, directives and clauses(sub classes are seperated).

Is this change in this patch?



================
Comment at: flang/lib/Semantics/check-omp-structure.cpp:21
+
+#define CHECK_REQ_CONSTANT_SCALAR_INT_CLAUSE(X, Y) \
+  void OmpStructureChecker::Enter(const parser::OmpClause::X &c) { \
----------------
The name is a bit misleading since it does CheckAllowed also.

Nit: seperate -> separate. Used in a few other places and in the summary.
