; Verify that the slow/fast unaligned memory attribute is set correctly for each CPU model.
; Slow chips use 4-byte stores. Fast chips with SSE or later use something other than 4-byte stores.
; Chips that don't have SSE use 4-byte stores either way, so they're not tested.
; Also verify that SSE4.2 or SSE4a imply fast unaligned accesses.
