[lit] Use argparse instead of optparse Summary: optparse is deprecated in Python 2.7, which is the minimum version of Python required to run the LLVM test suite. Replace its usage in lit with argparse, optparse's 2.7 replacement module. argparse has several benefits over optparse, but this commit does not make use of those benefits yet. Instead, it simply uses the new API, and attempts to keep the number of changes to a minimum. Confirmed that lit's test suite, as well as LLVM's regression test suite, still pass with these changes.
