  -----------
  [RISCV][GlobalISel] Legalize add, sub and binary logical instructions for narrow types

For rv32, we test the legalization of i8, i16 and i32. For rv64, we additionally test the legalization of i64.

This is the first of a series of commits aiming to legalize arithmetic instructions for RISCV.
