[ tree-ssa ] EON fix

[law@redhat.com]

Whee.  This should fix the problems with EON from SPEC2000 tripping an
internal sanity check in the tree-ssa code.

The executive summary is we weren't gimplifying the cleanup 
associated with a TARGET_EXPR.  Wow.

Bootstrapped and regression tested.

	* gimplify.c (simplify_target_expr): Make sure to simplify
	the cleanup too.
