it's almost certainly untested for years.

dwarf2out: Emit NOTE_INSN_CFI_* both with and without cfi-asm.

This patch is essentially Bernd's 006-cfilabel patch, updated
for all the other changes to dwarf2out.

The patch reduces the difference between the cfi-asm and non-cfi-asm
code paths.  We now emit the CFI notes in all cases.  Later, after we're
done producing the CFI insns we need, another pass over the rtl adds
the necessary labels and set_loc/advance_loc CFIs.  One consequence of
this is that def_cfa_1 can no longer use lookup_cfa, so it just compares
to an old_cfa variable instead.

The major change since Bernd's patch is that all the target-specific
changes are no longer necessary.

        * dwarf2cfi.c (add_cfi): Remove.
        (dwarf2out_cfi_label): Remove force argument.  Only generate the
        label name.
        (add_fde_cfi): Simplify the different code paths.
        (add_cie_cfi): New.
        (old_cfa, old_cfa_remember): New.
        (def_cfa_1, reg_save): Remove label, add for_cie parameter.
        (last_reg_save_label): Remove.
        (dwarf2out_args_size, dwarf2out_stack_adjust, queue_reg_save,
        dwarf2out_frame_debug_def_cfa, dwarf2out_frame_debug_adjust_cfa,

dwarf2out: Move insn scanning out of final.c.

This patch is essentially Bernd's 005-scanfirst patch, updated for
the introduction of the dwarf2cfi.c file.

We introduce NOTE_INSN_CFI and NOTE_INSN_CFI_LABEL to hold the dwarf2
info during the bulk of final.  The actual construction of these notes
still happens during final, right at the very beginning of the pass,
via the dwarf2out_frame_debug_init hook.

        * dwarf2cfi.c (cfi_insn): New.
        (dwarf2out_cfi_label): Don't emit cfi label here.
        (add_fde_cfi): Create a NOTE_INSN_CFI.
        (dwarf2out_frame_debug): Setup cfi_insn.

dwarf2out: Split CFI construction routines into a new file.

Excepting changing some functions from static to extern, this
patch contains code motion only.  The split is not very clean
at this point, but will be refined as CFI construction is turned
into its own proper pass.
