llvm-project/llvm/test/Transforms/SimplifyCFG
Jakob Stoklund Olesen 977f41a1fa Also optimize large switch statements.
The isValueEqualityComparison() guard at the top of SimplifySwitch()
only applies to some of the possible transformations.

The newer transformations work just fine on large switches, and the
check on predecessor count is nonsensical.
