[patch] Remove call to tidy_fallthru_edge in tree-inline.c

[Eric Botcazou]

Hi,

tidy_fallthru_edges contains RTL-specific bits:

	  if (! (s->flags & EDGE_COMPLEX)
	      && s->dest == c
	      && !find_reg_note (BB_END (b), REG_CROSSING_JUMP, NULL_RTX))
	    tidy_fallthru_edge (s);

so it is disabled at the GIMPLE level.  That's why I don't think that calling 
it from tree-inline.c makes much sense.

Tested on i586-suse-linux, OK for mainline?

	* cfghooks.c (tidy_fallthru_edges): Add ??? comment.
	* tree-inline.c (delete_unreachable_blocks_update_callgraph): Remove
	call to tidy_fallthru_edges.
