patch to enable response file support in ParseCommandLineOptions

Hi,

I am sending a patch to enable response file support in ParseCommandLineOptions. With this change, all llvm tools will support response file. This helps overcome the command line length limit which we encountered recently.

Index: include/llvm/Support/CommandLine.h

Hi Sam, please add a testcase. Does this cause any regressions?

Ciao, Duncan.

Hi Duncan,

The patch for the test and the change is attached. I ran the regression test and no regressions found.
