  -----------
  [RISCV] Add some tests for SimplifyCFG's switch to lookup table transform

These are some of the basic cases taken from X86.

We currently fail to use lookup tables on many of these cases
because SimplifyCFG requires a legal type to do the transform and
RISCV only has one legal integer type.
