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
