* expr.c (can_store_by_pieces): Return true if length is zero.
(store_by_pieces): If length is zero and endp is two, abort,
othwerise, if length is zero and endp is not two, return "to".
(clear_by_pieces): Do nothing if length is zero.
(clear_storage): Do nothing if length is zero.
(store_constructor): Simplify code when size is zero, or the
target has already been cleared. This avoids emitting a
blockage instruction when initializing empty structures.
* g++.dg/opt/emptyunion.C: New testcase.
