I didn't find anything using EDGE_DFS_BACK in RTL infrastructure
used by var-tracking or var-tracking itself, the following removes
this computation.

Bootstrapped and tested on x86_64-unknown-linux-gnu.

I'll push this on Monday unless somebody points out my obvious mistake.

Richard.

	* var-tracking.c (variable_tracking_main_1): Remove call
	to mark_dfs_back_edges.
