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.

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

still happens during final, right at the very beginning of the pass,
via the dwarf2out_frame_debug_init hook.
