Chuanqi Xu ce2257d69f [C++20] [Modules] Judge current module correctly 
Now the implementation would accept following code:
```
//--- impl.cppm
module M:impl;
class A {};

//--- M.cppm
export module M;
import :impl;

//--- Use.cpp
import M;
void test() {
    A a; // Expected error. A is not visible here.
}
```

which is clearly wrong.  The root cause is the implementation of
`isInCurrentModule` would return true if the module is a partition! So
in the above example, although Use.cpp is not a module unit,
`isInCurrentModule ` would still return true when the compiler tries to
see if the owning module of `A` is the current module. I believe this is
an oversight. This patch tries to fix this problem.

//===----------------------------------------------------------------------===//
// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

Information on Clang:             http://clang.llvm.org/

If you have questions or comments about Clang, a great place to discuss them is
on the Clang forums:

If you find a bug in Clang, please file it in the LLVM bug tracker:
