The ALLOCATORS construct is one of the few constructs that require a special form of the associated block. Convert the AST node to use OmpDirectiveSpecification for the directive and the optional end directive, and to use parser::Block as the body: the form of the block is checked in the semantic checks (with a more meaningful message).
