Read experimental suspend functional types as suspend

Browse Source 
Before 1.6 we wrote suspend functional types with last parameter of
kotlin.coroutines.experimental.Continuation type to .kotlin_metadata
files. For example, kotlin-stdlib-common. Thus, we need to read
them, since coroutines have been released in 1.3 and we need to be able
to read stable binaries.
