poly_int: lra frame offsets
This patch makes LRA use poly_int64s rather than HOST_WIDE_INTs
to store a frame offset (including in things like eliminations).

gcc/
* lra-int.h (lra_reg): Change offset from int to poly_int64.
(lra_insn_recog_data): Change sp_offset from HOST_WIDE_INT
to poly_int64.
(lra_eliminate_regs_1, eliminate_regs_in_insn): Change
update_sp_offset from a HOST_WIDE_INT to a poly_int64.
(lra_update_reg_val_offset, lra_reg_val_equal_p): Take the
offset as a poly_int64 rather than an int.
* lra-assigns.c (find_hard_regno_for_1): Handle poly_int64 offsets.
(setup_live_pseudos_and_spill_after_risky_transforms): Likewise.
* lra-constraints.c (equiv_address_substitution): Track offsets
as poly_int64s.
(emit_inc): Check poly_int_rtx_p instead of CONST_INT_P.
(curr_insn_transform): Handle the new form of sp_offset.
* lra-eliminations.c (lra_elim_table): Change previous_offset
and offset from HOST_WIDE_INT to poly_int64.
(print_elim_table, update_reg_eliminate): Update accordingly.
(self_elim_offsets): Change from HOST_WIDE_INT to poly_int64_pod.
(get_elimination): Update accordingly.
(form_sum): Check poly_int_rtx_p instead of CONST_INT_P.
(lra_eliminate_regs_1, eliminate_regs_in_insn): Change
update_sp_offset from a HOST_WIDE_INT to a poly_int64. Handle
poly_int64 offsets generally.
(curr_sp_change): Change from HOST_WIDE_INT to poly_int64.
(mark_not_eliminable, init_elimination): Update accordingly.
(remove_reg_equal_offset_note): Return a bool and pass the new
offset back by pointer as a poly_int64.
* lra-remat.c (change_sp_offset): Take sp_offset as a poly_int64
rather than a HOST_WIDE_INT.
(do_remat): Track offsets poly_int64s.
* lra.c (lra_update_insn_recog_data, setup_sp_offset): Likewise.
