dwarf2cfi: Generate and connect traces.
This kinda-sorta corresponds to Bernd's 007-dw2cfi patch. Certainly
the same concepts of splitting the instruction stream into extended
basic blocks is the same. This patch does a bit better job with the
documentation. Also, I'm a bit more explicit about matching things
up with the similar code from the regular CFG routines.
What's missing at this point is any attempt to use DW_CFA_remember_state.
I've deferred that for the moment because it's easy to test the state
change code across epilogues, whereas the shrink-wrapping code is not
in this tree and section switching is difficult to force.
* dwarf2cfi.c: Include basic-block.h.
(dw_label_info): Remove.
(trace_work_list, trace_index): New.
(remember_row, emit_cfa_remember): Remove.

(save_point_p): New.
(free_cfi_row): Remove.
(add_cfi): Do not emit DW_CFA_remember_state.
(cfa_row_equal_p): New.
(barrier_args_size): Remove.
(compute_barrier_args_size_1, compute_barrier_args_size): Remove.
(dwarf2out_notice_stack_adjust): Don't compute_barrier_args_size.
(maybe_record_trace_start, create_trace_edges, scan_trace): New.
(dwarf2out_cfi_begin_epilogue): Remove.
(dwarf2out_frame_debug_restore_state): Remove.
(connect_traces, create_pseudo_cfg): New.
(create_cfi_notes, execute_dwarf2_frame): Rewrite using traces.
