cfgloop.h (DLTHE_RECORD_COPY_NUMBER): New flag.
* cfgloop.h (DLTHE_RECORD_COPY_NUMBER): New flag.
* cfgloopmanip.c (duplicate_loop_to_header_edge): Set aux flags only
when asked for.
* loop-unroll.c (peel_loop_completely, unroll_loop_constant_iterations,
unroll_loop_runtime_iterations, peel_loop_simple, unroll_loop_stupid):
Update call of duplicate_loop_to_header_edge.
(apply_opt_in_copies): Clear out aux pointers.
