The analyzer needs to support suppressing warnings like the linker does. RUC already works, but we still need to add support for UnconditionalSuppressMessage and probably also adding both of these attributes via XML.
edit: UnconditionalSuppressMessage should already be working since roslyn supports it natively - so for non-attribute suppressions we should only need to turn on the existing tests.
@jtschuster is working on attribute XML support so you might want to sync with him @LakshanF
