  Log Message:
  -----------
  [Flang] Fix error messages on Windows.

Flang uses positional arguments for `messages::say()`, such as "%1$s" which is only supported in MS Compilers with the `_*printf_p` form of the function. This uses a conditional macro to convert the existing `vsnprintf` used to the one needed in MS-World.

7 tests in D107575 rely on this change.
