ARM64: make sure first argument to INSERT_SUBVECTOR has right type.
Again, coalescing and other optimisations swiftly made the MachineInstrs consistent again, but when compiled at -O0 a bad INSERT_SUBREGISTER was produced. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205423 91177308-0d34-0410-b5e6-96231b3b80d8
