[PATCH] Fix PR middle-end/PR24589

[Andrew Pinski <pinskia at physics dot uc dot edu>]

The problem here is that we gimplify the
expression for side effects but don't actually add the expression
if the gimplify put it back in the same expression.

OK? Bootstrapped and tested on x86_64-pc-linux-gnu with no regressions.

ChangeLog:


	* gimplify.c (gimplify_expr) <case CONSTRUCTOR>: Add the
	expressions to a statement list instead of gimplifying them.


testsuite/ChangeLog:

	* gcc.c-torture/execute/zero-struct-2.c: New test.
