[DAGCombiner] Fix a case of 1 in non-splat vector pow2 divisor

[aheejin]

Summary

D42479 (rL329525) enabled SDIV combine for pow2 non-splat vector
dividers. But when there is a 1 in a vector, the instruction sequence to
be generated involves shifting a value by the number of its bit widths,
which is undefined.

Especially, in architectures that do not support vector instructions,
each of element in a vector will be computed separately using scalar
operations, and then the resulting value will be undef for '1' values
in a vector.

(All 1's vector is fine; only vectors mixed with 1 and others will be
affected.)
