cgraphunit.c (cgraph_redirect_edge_call_stmt_to_callee): Chain the new statement and adjust VDEF only if necessary.

Browse Source 
* cgraphunit.c (cgraph_redirect_edge_call_stmt_to_callee): Chain the
	new statement and adjust VDEF only if necessary.  Remove superfluous
	call to maybe_clean_or_replace_eh_stmt.
	* gimple.c (gimple_call_copy_skip_args): Use gimple_call_copy_flags to
	copy the flags.
	* gimple-iterator.c (gsi_replace): Clear BB of old statement here...
	* tree-inline.c (copy_bb): ...and not there.
