re PR c/36489 (Warning "initialized field overwritten" wrongly triggers with multidimensional arrays)

	PR c/36489
	* c-typeck.c (add_pending_init): Add IMPLICIT argument.  Only
	warn about overwriting initializer with side-effects or
	-Woverride-init if !IMPLICIT.
	(output_init_element): Likewise.  Pass IMPLICIT down to
	add_pending_init.
	(process_init_element): Add IMPLICIT argument.  Pass it down
	to output_init_element.
	(push_init_element, pop_init_level, set_designator): Adjust
	process_init_element callers.
	(set_nonincremental_init, set_nonincremental_init_from_string):
	Adjust add_pending_init callers.
	(output_pending_init_elements): Adjust output_init_element callers.
	* c-tree.h (process_init_element): Adjust prototype.
	* c-parser.c (c_parser_initelt, c_parser_initval): Adjust
	process_init_element callers.

	* gcc.dg/pr36489.c: New test.
