[llvm] r228027 - Fixed signed/unsigned comparison warning.

[Chad Rosier]

Hi Simon,
MVT::getVectorNumElements() has an 'unsigned' return type.

Would it make more sense to change NumElements to unsigned and fix the
induction variables for those loops that compare NumElements, rather than
using a cast in the assert?
