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.
