ENH: Identify Fortran compilers with fixed format

This enhances the Fortran compiler id detection by using a source that can compile either as free or fixed format. As long as the compiler knows it should preprocess the source file (.F) the identification can work. Even free-format compilers may try fixed-format parsing if the user specifies certain flags, so we must support both.
