Log message:
	(thumb_find_work_register): Check all of the argument registers to see if they
	are free, and a couple of special cases where the last argument register but
	can be proved to be available during the function's prologue.
	(print_multi_reg, arm_compute_save_reg0_reg12_mask, output_return_instruction,
	emit_multi_reg_push, thumb_pushpop, thumb_unexpanded_epilogue): Use unsigned
	long as the type for the register bit-mask.
	(thumb_compute_save_reg_mask): Likewise.  Also use thumb_find_work_register()
	to ensure that there is agreement about which work register is going to be
	used in the prologue.
	(thumb_output_function_prologue): Use unsigned long as the type	for the
	register bit-mask.  Also delay pushing the link register if other high
	registers are going to be pushed.
	(thumb_compute_save_reg_mask, emit_multi_reg_push, print_multi-reg,
	number_of_first_bit_set, thumb_pushpop): Remove redundant prototypes.
