This patch introduce an automatic generation of the clause parser from the TableGen
information.
New information can be stored directly in the TableGen file:
- The different aliases that a clause support.
- prefix before a value.
- whether a prefix is optional or not.
Makes it easier to add new clauses and also avoid some error (`write` clause incorrect until now).
This patch is updating only the OpenACC part. A patch with a modification of the OpenMP clause parser will follow.
