OpenMP 6.0 has changed the modifiers on the MAP clause. Previous patch has introduced parsing support for them. This patch introduces processing of the new forms in semantic checks and in lowering. This only applies to existing modifiers, which were updated in the 6.0 spec. Any of the newly introduced modifiers (SELF and REF) are ignored.
