[X86] Do not lower scalar sdiv/udiv to a shifts + mul sequence when optimizing for minsize
There are some cases where the mul sequence is smaller, but for the most part,
using a div is preferable. This does not apply to vectors, since x86 doesn't
have vector idiv, and a vector mul/shifts sequence ought to be smaller than a
scalarized division.
