RFC: copy full value location

[Jim Blandy]

Daniel's said in private mail that this looked fine to him; I'll put
it up in case other folks have comments, and then commit.  (It's
almost obvious anyway.)

gdb/ChangeLog:
2006-12-07  Jim Blandy  <jimb@codesourcery.com>

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