David Stuttard 51c1b22806 [DAGCombine] Fix for shuffle to vector extend for non power 2 vectors 
Summary:
See https://llvm.org/PR33743 for more details

It seems that for non-power of 2 vector sizes, the algorithm can produce
non-matching sizes for input and result causing an assert.

This usually isn't a problem as the isAnyExtend check will weed these out, but
in some cases (most often with lots of undefined values for the mask indices) it
can pass this check for non power of 2 vectors.

Adding in an extra check that ensures that bit size will match for the result
and input (as required)
