Conditional conformances aren't quite ready yet for Swift 4.1, so introduce the flag `-enable-experimental-conditional-conformances` to enable conditional conformaces, and an error when one declares a conditional conformance without specifying the flag. Add this flag when building the standard library (which will vend conditional conformances) and to all of the tests that need it. Fixes rdar://problem/35728337.
