[Hexagon] Crash in instruction selection for insert_vector_elt for HVX
A wrong type was passed to insertVector, causing an out-of-bounds value to be added an an operand to HexagonISD::INSERT. This later failed in instruction selection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@320369 91177308-0d34-0410-b5e6-96231b3b80d8
