示例1: runOnModule
//
// Method: runOnModule()
//
// Description:
// Entry point for this LLVM pass. Search for insertvalue instructions
// that can be simplified.
//
// Inputs:
// M - A reference to the LLVM module to transform.
//
// Outputs:
// M - The transformed LLVM module.
//
// Return value:
// true - The module was modified.
// false - The module was not modified.
//

// Repeat till no change
