    Expose InsertPreheaderForLoop from LoopSimplify to other passes · a12d82b4
    Hal Finkel authored
    Other passes, PPC counter-loop formation for example, also need to add loop
    preheaders outside of the regular loop simplification pass. This makes
    InsertPreheaderForLoop a global function so that it can be used by other
    passes.
    
    No functionality change intended.
