[cfe-dev] disabling MS extensions on some tests

[John Thompson]

By adding -fms-extensions=0 to some of the tests previously failing on
Windows, it makes these 6 tests pass on Windows.

The question is, are these legitimate differences between the default Clang
behavior and MSVC?

They seem sort of reasonable, but I'm not knowledgeable enough to say for
sure.

The enclosed patch contains these changes.

Here is the previous test output:
