[swift-evolution] [Idea] #suppress(warning-identifier)

[Shawn Erickson]

I would prefer something like...

    #warn(no-warning-identifier)
    ...
    #warn(warning-identifier)

..to keep the warning identifier behavior the same in code and on the
command line.

The ability to push and pop warning modifications (set of) could also make
sense.
