[swift-evolution] [DRAFT] Introducing a Debug Build Configuration Test

[Erica Sadun]

I would like to update my draft proposal to introduce a test for debug configurations using a public function
rather than a build configuration test.

* Would the stdlib team be open to that? 
* What would be an appropriate name?  `debugConfiguration`? `debugBuild`? `isDebugBuild`? `isDebugConfiguration`?
