	* tree-ssa-pre.c (pre_expression): Free and allocate the
	ephi_pindex_htab and phi_pred_cache in this function only.
	(phi_pred_cache): New array to store cached phi preds, to avoid
	recomputation and unnecessary copying.
	(subst_phis): Use it.
	(added_phis): array of added phis that is marked for GC.
	
	* Makefile.in: Add tree-ssa-pre.c to the gtype files, and
	gt-tree-ssa-pre.h to the list of generated files.
