re PR middle-end/51389 (GCC uses up to 75GB of virtual memory)
PR middle-end/51389
* Makefile.in (tree-data-ref.o): Depend on $(PARAMS_H).
* tree-data-ref.h (find_data_references_in_loop): Remove declaration.
* tree-data-ref.c (find_data_references_in_loop): Make static.
(compute_all_dependences): Change return type to bool. Bail out
for too many datarefs in a loop. Move the hunk resetting the data
dependences vector from ...
(compute_data_dependences_for_loop): ... here. Account for
compute_all_dependences returning false.
(compute_data_dependences_for_bb): Likewise.
* params.def (PARAM_LOOP_MAX_DATAREFS_FOR_DATADEPS): New param.
* doc/invoke.texi (loop-max-datarefs-for-datadeps): Document it.
