Craig Topper 4e63db8387 [InstCombine] Fix incorrect usage of getPrimitiveSizeInBits when we should be using the element size for vectors ...

For vectors, getPrimitiveSizeInBits returns the full vector width. This code should using the element size for vectors. This could be fixed by calling getScalarSizeInBits, but its even easier to just get it from the APInt we're checking.
