just argv[0]. And remove the code for searching the current working directory and for searching PATH; the point of FindExecutable is not to find whatever version of the executable can be found by searching around, but to find an executable that accompanies the current executable. Update the tools to use sys::Program::FindProgramByName when they want PATH searching. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78240 91177308-0d34-0410-b5e6-96231b3b80d8
