[PATCH] Avoid shift in get_ref_base_and_extent

[Richard Biener via Gcc-patches]

This avoids one instance of a shift from bytes to bits in
get_ref_base_and_extent by using TYPE_SIZE instead of TYPE_SIZE_UNIT.

Bootstrapped and tested on x86_64-unknown-linux-gnu, pushed.

        * tree-dfa.cc (get_ref_base_and_extent): Avoid shift.
