Cameron McInally 06340b3cd4 [SVE] Lower fixed length vXi8/vXi16 SDIV to scalable
There are no nxv16i8/nxv8i16 SDIV instructions, so these fixed width operations must be promoted to nxv4i32.

++ SVE CodeGen Warnings ++

When the WARN check lines fail in the SVE codegen tests it most likely means you
have introduced a warning due to:
1. Adding an invalid call to VectorType::getNumElements() or EVT::getVectorNumElements()
   when the type is a scalable vector.
2. Relying upon an implicit cast conversion from TypeSize to uint64_t.

For generic code, please modify your code to work with ElementCount and TypeSize directly.
For target-specific code that only deals with fixed-width vectors, use the fixed-size interfaces.
Please refer to the code where those functions live for more details.
