* dwarf2out.c (dw_cfi_oprnd_struct): Reduce dw_cfi_reg_num to int.
(lookup_cfa_1): Apply data alignment to DW_CFA_def_cfa_offset_sf
and DW_CFA_def_cfa_sf.
(def_cfa_1): Use DW_CFA_def_cfa_offset_sf with negative values.
(dbx_reg_number): Don't assert particular registers here.
(based_loc_descr): ... do it here instead. Fold in ...
(eliminate_reg_to_offset): ... this function.
(compute_frame_pointer_to_cfa_displacement): Fold in the effects
of eliminate_reg_to_offset; use FRAME_POINTER_CFA_OFFSET.
* unwind-dw2.c (execute_cfa_program): Apply data align factor
to DW_CFA_def_cfa_offset_sf and DW_CFA_def_cfa_sf.
* function.c (instantiate_new_reg): Use FRAME_POINTER_CFA_OFFSET.
(instantiate_virtual_regs): Likewise.
* var-tracking.c (adjust_stack_reference): Likewise.
* doc/tm.texi (FRAME_POINTER_CFA_OFFSET): New.
