lra: A multiple_sets is not a simple_move_p (PR73650)
In the PR we have a PARALLEL of a move and a compare (a "mr." instruction).
The compare is dead, so single_set on it returns just the move. Then,
simple_move_p returns true; but the instruction does need reloads in this
case. This patch solves this by making simple_move_p return false for
every multiple_sets instruction.
PR rtl-optimization/73650
* lra-constraints.c (simple_move_p): If the insn is multiple_sets
it is not a simple move.
