re PR middle-end/85496 (internal compiler error: in emit_move_insn, at expr.c:3722)
PR middle-end/85496
* expr.c (store_field): In the bitfield case, if the value comes from
a function call and is returned in registers by means of a PARALLEL,
do not change the mode of the temporary unless BLKmode and VOIDmode.
