data-ref: Fix ranges_maybe_overlap_p test

Browse source 
dr_may_alias_p rightly used poly_int_tree_p to guard a use of
ranges_maybe_overlap_p, but used the non-poly extractors.
This caused a few failures in the SVE ACLE asm tests.

gcc/
	* tree-data-ref.cc (dr_may_alias_p): Use to_poly_widest instead
	of to_widest.
