* loop.c (this_loop_info): New variable.
(loop_has_call, loop_has_volatile, loop_has_tablejump,
loop_continue, loops_enclosed): Replace with fields in this_loop_info.
All uses updated.
(prescan_loop, strength_reduce): New argument loop_info. All callers
updated.
(scan_loop): New variable loop_info, initialise to address of
this_loop_info.
(prescan_loop): Set loop_info->vtop if find NOTE_INSN_LOOP_VTOP.
Delete variable loop_has_multiple_exit targets and replace with
field in this_loop_info.
(find_and_verify_loops): Rename this_loop to this_loop_num.
(strength_reduce): Delete loop_iteration_info. Replace variable
loop_info with function argument of same name.
(insert_bct): Rework test for loop being completely unrolled.
* loop.h (struct loop_info): New fields num, loops_enclosed,
has_call, has_volatile, has_tablejump, has_multiple_exit_targets,
has_indirect_jump, and cont. Redefine use of unroll_number.
(loop_unroll_number): Delete.
* unroll.c (unroll_loop): Store loop unroll count in unroll_number
field of loop_info.
(loop_iterations): Delete variable vtop and instead use
loop_info->vtop computed in prescan_loop.
