bool
isCriticalEdge(
    Instruction const* TI,
    unsigned int SuccNum,
    bool AllowIdenticalEdges = false);

Return true if the edge from TI to Succ is a critical edge.

bool
isCriticalEdge(
    Instruction const* TI,
    BasicBlock const* Succ,
    bool AllowIdenticalEdges = false);

True if the edge is critical.

Name	Description
TI	Terminator instruction that defines the edge source.
SuccNum	Zero-based successor index of the edge.
AllowIdenticalEdges	If true, identical edges are not critical.
Succ	Successor basic block that defines the edge destination.
