[X86][SSE] Fix for getScalarValueForVectorElement to detect scalar sources requiring truncation.

The fix ensures that scalar sources inserted into a vector are the correct bit size.

Integer scalar sources from BUILD_VECTOR and SCALAR_TO_VECTOR nodes may require truncation that this function doesn't currently support.
