[PATCH] D45685: [Sema] Add -wtest global flag that silences -Wself-assign for overloaded operators.

[David Blaikie via cfe-commits]

I'm not sure this is a practical direction to pursue - though perhaps
others disagree.

It's likely non-trivial to plumb a flag through most build systems to be
applied only to test code (& likely would suppress the warning in headers
only included in test code - so for example, in a header-only library if
the user ran their tests they wouldn't see the warning, but when the users
code was used in some other production code it might warn (& possibly break
the build if -Werror is in use))
