Writing a Jigsaw-modular Kotlin program which doesn't require
kotlin.stdlib doesn't make sense because it most likely will fail at
runtime, on access to anything from the standard library. Previously, we
checked that kotlin.stdlib was in the module graph, but that's not
enough, we should also check that the source module requires it.
'-Xallow-kotlin-package' can be used to disable the error.
Add a test checking that an indirect (transitive) dependency is also OK
If a path to the module-info.java file is passed as an argument, we
should treat all other source files passed as arguments (either as
individual source files or inside a source directory) as members of that
module. Previously we treated other source files as members of the
unnamed module, and this resulted in incorrect errors when using a
member exported with a qualification from another named module, for
example
