PATCH to avoid copying tail padding (was: GCC 3.2)

[Jason Merrill]

One more problem: we were using expr_size in store_one_arg to determine how
much space to push.  That amount should be determined by the size of the
type, not the data size of the expression.

Tested i686-pc-linux-gnu, applied trunk and 3.2 branch.

	* calls.c (store_one_arg): Use size_in_bytes to determine the
	amount of space to push.
