Misc conversions to vrange.

The following converts a handful of places that were irange centric.

Tested on x86-64 Linux.

gcc/ChangeLog:

	* gimple-range-fold.cc
	(fold_using_range::range_of_ssa_name_with_loop_info): Restrict the
	call to SCEV for irange supported types.
	(fold_using_range::range_of_builtin_int_call): Convert to vrange.
	* gimple-range.cc (gimple_ranger::prefill_stmt_dependencies): Same.
	* tree-ssa-dom.cc (cprop_operand): Same.
