m68k: replace reload_in_progress by reload_in_progress || lra_in_progress

For now assume that LRA needs the same treatment as reload.

	* config/m68k/m68k.md ("movsi", "movxf"): Replace
	reload_in_progress by reload_in_progress || lra_in_progress.
	* config/m68k/m68k.cc (m68k_legitimate_mem_p)
	(emit_move_sequence): Likewise.
	* config/m68k/predicates.md ("fp_src_operand"): Likewise.
