History
Hans Wennborg 7a301c1b8c SimplifyCFG: Correctly handle switch lookup tables which fully cover the input type and use bit tests to check for holes 
When using bit tests for hole checks, we call AddPredecessorToBlock to give the
phi node a value from the bit test block. This would break if we've
previously called removePredecessor on the default destination because the
switch is fully covered.

Test case by Mark Lacey.
