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.
