[PATCH] D21251: [TTI] The cost model should not assume illegal vector casts get completely scalarized

[Michael Kuperstein via llvm-commits]

Ah, it's a shame I missed D15604, would have saved me the trouble of
figuring out getTypeLegalizationCost() is mis-named.

Anyway, I think this patch should more or less take care of the type
legalization aspect of D15604.
Regarding the changes D15604 made in the cost table - was there a reason
you abandoned them? Or are they independently good?
