Subject: [PATCH 1/3] [flang][OpenMP] Implement flexible OpenMP clause
representation
Introduce a set of generic classes (templates) that represent OpenMP
clauses in a language-agnostic manner. OpenMP clauses can contain
expressions and data objects and the exact representation of each
depends on the source language of the compiled program. To deal with
this, the templates depend on two type parameters:
- IdType: type that represent object's identity (in a way that
satisfied OpenMP requirements), and
- ExprType: type that can represent numeric values, as well as
data references (e.g. x.y[1].z[2]).
In addition to that, implement code instantiating these templates
from flang's AST.
This patch only introduces the new classes, they are not yet used
anywhere.

Subject: [PATCH 2/3] [flang][OpenMP] Convert unique clauses in ClauseProcessor
Temporarily rename old clause list to `clauses2`, old clause iterator
to `ClauseIterator2`.
Change `findUniqueClause` to iterate over `omp::Clause` objects,
modify all handlers to operate on 'omp::clause::xyz` equivalents.

Subject: [PATCH 3/3] [flang][OpenMP] Convert repeatable clauses (except Map)
in ClauseProcessor
Rename `findRepeatableClause` to `findRepeatableClause2`, and make the
new `findRepeatableClause` operate on new `omp::Clause` objects.
Leave `Map` unchanged, because it will require more changes for it to
work.
