gdb/fortran: Implement la_print_typedef for Fortran
Implement an la_print_typedef method for Fortran, this allows 'info types' to work for Fortran. The implementation is just copied from ada_print_typedef (with the appropriate changes). To support the testing of this patch I added a new proc, fortran_character1, to lib/fortran.exp which returns a regexp to match a 1-byte character type. The regexp returned is correct for current versions of gFortran. All of the other regexp are guesses based on all of the other support procs in lib/fortran.exp, I haven't tested them myself. gdb/ChangeLog: * f-lang.c (f_language_defn): Use f_print_typedef. * f-lang.h (f_print_typedef): Declare. * f-typeprint.c (f_print_typedef): Define. gdb/testsuite/ChangeLog: * gdb.fortran/info-types.exp: New file. * gdb.fortran/info-types.f90: New file. * lib/fortran.exp (fortran_character1): New proc.
