Herald added a project: clang.

The test Frontend/plugin-delayed-template.cpp is failing when asserts are enabled because it hits an assertion in denormalizeStringImpl when trying to round-trip OPT_plugin_arg. Fix this by adjusting how the option is handled, as the first part is joined to -plugin-arg and the second is separate.
