loop.h (loop_insn_first_p): Declare.

	* loop.h (loop_insn_first_p): Declare.
	* loop.c (loop_insn_first_p): No longer static.
	* unroll.c (iteration_info) Fix comparison to
	reg_iv_type->num_elements.
	Before accessing reg_biv_class, check index against
	max_reg_before_loop.
	Fix and enable code for giv iterators.
	(loop_iterations): Compare with reg_iv_type->num_elements instead
	of with max_reg_before_loop.
