Valentin Clement 8f933a4e93 [openacc] Use TableGen enum for default clause value
Use the TableGen feature to have enum values for clauses.
Next step will be to extend the MLIR part used currently by OpenMP
to use the same enum on the dialect side.

This patch also add function that convert the enum to StringRef to be
used on the dump-parse-tree from flang.

Valentin Clement f4c8b80318 [openmp] Remove clause from OMPKinds.def and use OMP.td info
Remove the OpenMP clause information from the OMPKinds.def file and use the
information from the new OMP.td file. There is now a single source of truth for the
directives and clauses.

To avoid generate lots of specific small code from tablegen, the macros previously
used in OMPKinds.def are generated almost as identical. This can be polished and
possibly removed in a further patch.

Valentin Clement 9914a8737f [flang][openacc] Add parsing tests and semantic check for set directive
This patch add some parsing and clause validity tests for the set directive.
It makes use of the possibility introduces in patch D90770 to check the restriction
were one of the default_async, device_num and device_type clauses is required but also
not more than once on the set directive.

Valentin Clement a8a10acba2 [openacc][openmp] Allow duplicate between required and allowed once/exclusive
Validity check introduce in D90241 are a bit too restrict and this patch propose to losen
them a bit. The duplicate clauses is now check only between the three allowed lists and between the
requiredClauses and allowedClauses lists. This allows to enable some check where a clause can be
required but also appear only once on the directive. We found these kind of restriction useful
on the set directive in OpenACC for example.

Kiran Chandramohan e6c5e6efd0 [MLIR,OpenMP] Lowering of parallel operation: proc_bind clause 2/n
This patch adds the translation of the proc_bind clause in a
parallel operation.

The values that can be specified for the proc_bind clause are
specified in the OMP.td tablegen file in the llvm/Frontend/OpenMP
directory. From this single source of truth enumeration for
proc_bind is generated in llvm and mlir (used in specification of
the parallel Operation in the OpenMP dialect). A function to return
the enum value from the string representation is also generated.
A new header file (DirectiveEmitter.h) containing definitions of
classes directive, clause, clauseval etc is created so that it can
be used in mlir as well.

Valentin Clement d90443b1d9 [openmp] Base of tablegen generated OpenMP common declaration
Summary:
As discussed previously when landing patch for OpenMP in Flang, the idea is
to share common part of the OpenMP declaration between the different Frontend.
While doing this it was thought that moving to tablegen instead of Macros will also
give a cleaner and more powerful way of generating these declaration.
This first part of a future series of patches is setting up the base .td file for
DirectiveLanguage as well as the OpenMP version of it. The base file is meant to
be used by other directive language such as OpenACC.
In this first patch, the Directive and Clause enums are generated with tablegen
instead of the macros on OMPConstants.h. The next pacth will extend this
to other enum and move the Flang frontend to use it.
