--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
I've been thinking about this transformation, not just for sizes of 2 but for
larger objects as well. Looks like Clang 5 and later implements it for powers
2 up to 16 and does something slightly more involved for other small sizes of
10 bytes and less.
