re PR bootstrap/38578 (fatal warning during bootstrap on arm.c for output_move_double...

	PR bootstrap/38578
	* arm.c (load_multiple_sequence): Initialize ORDER array.
	(store_multiple_sequence): Likewise.
	(output_move_double): Make reg0 unsigned.
	(arm_output_epilogue): Make amount unsigned.
	(arm_expand_prologue): Move declaration of dwarf before block
	statements.
