[OpenMP] Implement EnumSet container

This is close to flang's common::EnumSet with the difference being that
it provides forward iterators.

The reason for having an implementation that is separate from
common::EnumSet is that this is intended to be shared for all consumers
of llvm/lib/Frontend/OpenMP. This class is also planned to be one of the
core containers for representing auto-generated OpenMP data in the future.

[flang][OpenMP] Use llvm::omp::ClauseSet instead of common::EnumSet

Replace uses of OmpClauseSet (defined in terms of common::EnumSet)
with the common llvm::omp::ClauseSet (defined via llvm::EnumSet).

[flang][OpenMP] Use llvm::omp::DirectiveSet instead of common::EnumSet

Replace uses of OmpDirectiveSet (defined in terms of common::EnumSet)
with the common llvm::omp::DirectiveSet (defined via llvm::EnumSet).

The llvm::omp::DirectiveSet class will also be used in openmp-parsers,
where OmpDirectiveSet was an instance of llvm::Bitset.

Git commit 7c761d4c5ab989dee5d51fb57678143fe6f67bde by Krzysztof Parzyszek on 22/07/2026 at 17:15..
[flang] Provide "clause set" type as parameter to DirectiveStructureChecker

This will remove the hardcoded dependence of DirectiveStructureChecker on
the common::EnumSet class. Both consumers of it will be able to use their
own type for the clause set.

The only complication was the ClauseSetToString member function, whose
implementation depended on the specifics of common::EnumSet, namely the
IterateOverMembers member function. It was moved out of the class, and
turned into a function template to make it possible to provide different
specializations for common::EnumSet and llvm::EnumSet.

[flang][OpenMP] Switch TableGen generation to use llvm::EnumSet

Replace the remaining uses of the common::EnumSet-based OmpClauseSet to
llvm::omp::ClauseSet.
