[flang] disable failing test

This test has been failing on Windows for multiple consecutive days without any action taken. This prevents our CI from finding other problematic tests.

That is right. @ftynse, it looks like your patch is based on an LLVM head that is week old and does not contain the fix.

I guess the pre-merge CI will fail for patch based on a head that predates the fix, sorry for that (The underlying issue in the code was very very old, more than two years old, but was exposed only recently, probably because the windows CI compiler version/conf changed and started optimized the code more, leading to a segfault).

Anyway, if you see failures on pre-merge CI on patches based on head including #83768, please feel free to reopen #83534 and revert #83822 (but it will not make any difference for patch based on heads without reverts).
