OpenMP: Allow complete replacement of clause during map/to/from expansion

At present, map/to/from clauses on OpenMP "target" directives may be
expanded into several mapping nodes if they describe array sections with
pointer or reference bases, or similar.  This patch allows the original
clause to be replaced during that expansion, mostly by passing the list
pointer to the node to various functions rather than the node itself.

This is needed by the following patch. There shouldn't be any functional
changes introduced by this patch itself.
