LRA outputs a lot debug information about insns.  I found that using 
slim insn/rtl presentation helps a lot for LRA debuging. The following 
patch makes slim presentation printing functions visible to LRA.  It 
also implements one more such function.

     * rtl.h (debug_bb_n_slim, debug_bb_slim, print_value_slim): New
     prototypes.
     (debug_rtl_slim, debug_insn_slim): Ditto.
     * sched-vis.c (print_value_slim): New.
