The fix for http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24306 breaks -m64
struct-layout-1.c.
It breaks the abi of every target, which is wrong. On ppc -m64, it results in
a self inconsistent abi.
This correct fix would be to modify ix86_function_arg_boundary function to give
PARM_BOUNDARY for zero sized objects.
