This patch makes value_primitive_filed copy full value->location, not just
VALUE_ADDRESS -- just the same that Jim has done to value_copy. 
No changes in behaviour so far and no regressions on x86. OK?

	* value.c (value_primitive_field): Copy the full 'location' contents, instead
        of assuming that copying ADDRESS will bring over everything in the
        union.  Remove obsolete comment.
