  [SimplifyCFG] Make test more robust (NFC)

These are supposed to test creation of a switch, so make sure
there is some actual code in the branches. Otherwise this could
be turned into a select instead.

  Log Message:
  -----------
  [SimplifyCFG] Add switch-to-select test with two equal cases (NFC)

We handle the case where we have two cases and a default all having
different values, but not the case where two cases happen to have
the same one.

The PhaseOrdering test is a particularly bad example where this
showed up.
