[Clang][OpenMP] Emit dependent PreInits before directive.
The PreInits of a loop transformation (atm moment only tile) include the computation of the trip count. The trip count is needed by any loop-associated directives that consumes the transformation-generated loop. Hence, we must ensure that the PreInits of consumed loop transformations are emitted with the consuming directive.
This is done by addinging the inner loop transformation's PreInits to the outer loop-directive's PreInits. The outer loop-directive will consume the de-sugared AST such that the inner PreInits are not emitted twice. The PreInits of a loop transformation are still emitted directly if its generated loop(s) are not associated with another loop-associated directive.
