[Bug objc/36580] New: ICE at -O2 and above (with strict aliasing) with invalid Objective-C code.

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Testcase:
struct objc_class { } ;
object_get_class(id object)
{
  (Class)object;
}
struct objc_class {};

--- CUT ---
We get:
IMP.mi:6: error: redefinition of 'struct objc_class'
IMP.mi:6: internal compiler error: in layout_type, at stor-layout.c:1878
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

I don't know if this is a regression of not.  I found this while testing the
tuples branch which included the wrong include directories and messed up the
code.
