re PR middle-end/29609 (Even with -O0 -g gcc optimizes a goto away and I cannot debug)

PR debug/37616
* basic-block.h (struct edge_def): Add goto_block field.
* cfglayout.c (fixup_reorder_chain): Ensure that there is at least
one insn with locus corresponding to edge's goto_locus if !optimize.
* profile.c (branch_prob): Copy edge's goto_block.
* cfgrtl.c (force_nonfallthru_and_redirect): Use goto_locus for
emitted jumps.
(cfg_layout_merge_blocks): Emit a nop with edge's goto_locus
locator in between the merged basic blocks if !optimize and needed.
* cfgexpand.c (expand_gimple_cond): Convert goto_block and
goto_locus into RTL locator. For unconditional jump use that
locator for the jump insn.
(expand_gimple_cond): Convert goto_block and goto_locus into
RTL locator for all remaining edges. For unconditional jump
use that locator for the jump insn.
* cfgcleanup.c (try_forward_edges): Avoid the optimization if
there is more than one edge or insn locator along the forwarding
edges and !optimize. If there is just one, set e->goto_locus.
* tree-cfg.c (make_cond_expr_edges, make_goto_expr_edges): Set also
edge's goto_block.
(move_block_to_fn): Adjust edge's goto_block.
