- Add a fatal error handler that can print a message with source location
before aborting.
- Update TODO macro to take an mlir location argument and to use the
newly introduced fatal error handler.
- Introduce TODO_NOLOC for the few places where no source location is
easily accessible.

The TableGen emitter for directives has two slots for flangClass information and this was mainly
to be able to keep up with the legacy openmp parser at the time. Now that all clauses are encapsulated in
AccClause or OmpClause, these two strings are not necessary anymore and were the the source of couple
of problem while working with the generic structure checker for OpenMP.
This patch remove the flangClassValue string from DirectiveBase.td and use the string flangClass as the
placeholder for the encapsulated class.

After discussion in `D93482` we found that the some of the clauses were not
following the common OmpClause convention.
The benefits of using OmpClause:
- Functionalities from structure checker are mostly aligned to work with
`llvm::omp::Clause`.
- The unparsing as well can take advantage.
- Homogeneity with OpenACC and rest of the clauses in OpenMP.
- Could even generate the parser with TableGen, when there is homogeneity.
- It becomes confusing when to use `flangClass` and `flangClassValue` inside
TableGen, if incase we generate parser using TableGen we could have only a
single `let expression`.
This patch makes `OmpProcBindClause` clause part of `OmpClause`.
The unparse function is dropped as the unparsing is done by `WALK_NESTED_ENUM`
for `OmpProcBindClause`.

From OMP 5.0 [2.17.8]
Restriction:
If memory-order-clause is release,acquire, or acq_rel, list items must not be specified on the flush directive.

This patch introduce the separate parser for the memory-order-clause from the general
OmpClauseList. This parser still creates OmpClause node and therefore can use all the feature
from TableGen and the OmpStructureChecker.
This is applied only for the Flush construct in this patch and it should be applied for
atomic as well.
This is the approach we disscussed several time during the weekly call.

This patch lower `!OMP PARALLEL` construct from PFT to OpenMPDialect operations.
This is first patch in this direction(lowering parallel construct).
OpenMP parallel construct can have multiple clauses and parameters. This patch
only implements lowering of an empty(contains no code in body) parallel construct
without any clauses or parameters.
Patch is carved out of following approved PR:

The lowering bridge will call these lowering hooks to process the Open
MP directives that it iterates over in the PFT. This is a mock
interface without an implementation in this patch.
