Cleanup range of address calculations.

Cleanup range of address calculations.

Align EVRP and ranger for how ranges of ADDR_EXPR are calculated.

	gcc/
	* gimple-range.cc: (gimple_ranger::range_of_range_op): Check for
	ADDR_EXPR and call range_of_address.
	(gimple_ranger::range_of_address): Rename from
	range_of_non_trivial_assignment and match vrp_stmt_computes_nonzero.
	* gimple-range.h: (range_of_address): Renamed.
	* range-op.cc: (pointer_table): Add INTEGER_CST handler.
	gcc/testsuite/
	* gcc.dg/tree-ssa/pr78655.c: New.
