[PATCH] D40699: Split IndirectBr critical edges before PGO gen/use passes.

> The PGO gen/use passes currently fail with an assert failure if there's a critical edge whose source is an IndirectBr instruction.

findIBRPredecessor will fail for blocks with multiple multiple indirectbr predecessors.  And then you're back at square one, with an assertion failure.
