While the compiler can bridge C block types to Swift function types, the Swift runtime cannot. Don't bridge block types to Swift function types in Objective-C generic arguments, so NSArray<some-block-type> will get imported as [@convention(block) (...) -> Whatever] rather than [(...) -> Whatever] Fixes rdar://problem/40879067 in a fairly narrow way; the Clang importer's approach to adjusting types based on context needs a cleanup, but this is the safe, localized fix suitable for 4.2.
