Do not clear bb->aux in duplicate_loop_body_to_header_edge
duplicate_loop_body_to_header_edge clears bb->aux which is not wanted
by a new use in loop unswitching. The clearing was introduced with
r0-69110-g6580ee7781f903 and it seems accidentially so.

* cfgloopmanip.cc (duplicate_loop_body_to_header_edge): Do
not clear bb->aux of the copied blocks.
