Summary Fix the test runner to correctly set PATH for shared libs on Windows
OS Windows NT
Component All Bugs
We sometimes test executables that link against shared libraries. In this case the executable and shared libraries are built separately, and not always in the same location. The executable needs to be able to find the shared library at runtime. This needs to be fixed by setting an appropriate PlatformContext in lldbtest.py for Windows that adds the shared library folder to PATH, rather than setting it to null.
