-/// PrependMainExecutablePath - Prepend the path to the program being executed
-/// to \p ExeName, given the value of argv[0] and the address of main()
-/// itself. This allows us to find another LLVM tool if it is built in the same
-/// directory. An empty string is returned on error; note that this function
-/// just mainpulates the path and doesn't check for executability.
-/// @brief Find a named executable.
