Implement dwarf2 exception handling for the ARM.
* config/arm/arm.h (INCOMING_RETURN_ADDR_RTX): Define.
(DWARF_FRAME_RETURN_COLUMN): Define.
* config/arm/arm.c (emit_multi_reg_push): Return rtx. Attach
REG_FRAME_RELATED_EXPR note.
(emit_sfm): Likewise.
(arm_expand_prologue): Set RTX_FRAME_RELATED_P on everything.
* dwarf2out.c (reg_save): Handle saving a register to itself.
(dwarf2out_frame_debug_expr): Handle an intermediate cfa reg.
* except.c (eh_regs): Don't use the static chain reg if it's
callee-saved.
* frame.h (frame_state): Add cfa_saved field.
* frame.c (execute_cfa_insn): Set it.
* libgcc2.c (throw_helper): Don't adjust sp if it's restored in
the epilogue.
* function.c (ARG_POINTER_CFA_OFFSET): Default to FIRST_PARM_OFFSET.
Now takes a parm.
(instantiate_virtual_regs): Adjust.
* tm.texi: Adjust.
* config/m68k/m68k.h (ARG_POINTER_CFA_OFFSET): Don't define.
* config/ns32k/ns32k.h (ARG_POINTER_CFA_OFFSET): Don't define.
* config/sparc/sparc.h (ARG_POINTER_CFA_OFFSET): Take a parm.
* dwarf2out.c (reg_number): Refer to FIRST_PSEUDO_REGISTER.
(initial_return_save): Use DWARF_FRAME_REGNUM, not reg_number.
