Fix -Wlarge-by-value-copy option handling in the driver. CC1 supports only the joined format. llvm-svn: 156161

Warn about -Wno-foo where foo is an unknown warning option. This is helpful for subtle misspellings such as -Wno-unused-command-line-arguments instead of -Wno-unused-command-line-argument. Also fix the diagnostic messages to properly handle -Wno- options. Previously, the positive version was always emitted (i.e., -Wfoo was emitted for -Wno-foo). rdar://11461500 llvm-svn: 156937

// Check that -isysroot warns on nonexistent paths.
Add some entropy to the folder name in Driver/warning-options.cpp. It was trying to check that things behave correctly when a non-existant folder was specified for -isysroot. Incidentally, I have a folder named FOO in the root of my drive, so this test was failing. Make this impossible by using %T to refer to a definitely non-existant folder.: llvm-svn: 281998
