The following patch adds a code neccessary for correct work of LRA

* loop-invariant.c (calculate_loop_reg_pressure): Pass new
argument to ira_setup_eliminable_regset.
* haifa-sched.c (sched_init): Pass new argument to
ira_setup_eliminable_regset.
* dwarf2out.c: Include lra.h.
(based_loc_descr, compute_frame_pointer_to_fb_displacement): Use
lra_eliminate_regs for LRA instead of eliminate_regs.
* ira.c: (ira_setup_eliminable_regset): Add parameter. Remove
need_fp. Call lra_init_elemination and mark
HARD_FRAME_POINTER_REGNUM as living forever if
frame_pointer_needed.
(ira): Call ira_setup_eliminable_regset with a new
argument.
* ira.h (ira_setup_eliminable_regset): Add an argument.
* Makefile.in (dwarf2out.o): Add dependence on ira.h and lra.h.
This is OK. Obviously it's useless without 7a/7b. But I just wanted to
go ahead and review the ancillary bits before going to the meat of the
submission.
So it's just the 7a/7b patch that needs review, right?
