explow.c:update_nonlocal_goto_save_area does not construct an object with the
mode specified by STACK_SAVEAREA_MODE macro. This causes
explow.c:emit_stack_save() to ICE when the modes do not match.

The problem is that update_nonlocal_goto_save_area does not really enforce what it says it should:
/* The nonlocal_goto_save_area object is an array of N pointers. The
first one is used for the frame pointer save; the rest are sized by
STACK_SAVEAREA_MODE. Create a reference to array index 1, the first
of the stack save area slots. */
t_save = build (ARRAY_REF, ptr_type_node, cfun->nonlocal_goto_save_area,
integer_one_node);
Note on PPC, STACK_SAVEAREA_MODE is not the default of Pmode.
Richard, can you look into this.

The patch at least solves "gcc.c-torture/execute/nestfunc-5.c", did not try the rest though
or a full bootstrap yet.
