gdb/fortran: add support for RANK keyword
gfortran supports the RANK keyword, see: https://gcc.gnu.org/onlinedocs/gfortran/RANK.html#RANK this commit adds support for this keyword to GDB's Fortran expression parser. gdb/ChangeLog: * f-exp.h (eval_op_f_rank): Declare. (expr::fortran_rank_operation): New typedef. * f-exp.y (exp): Handle UNOP_FORTRAN_RANK after parsing an UNOP_INTRINSIC. (f77_keywords): Add "rank" keyword. * f-lang.c (eval_op_f_rank): New function. * std-operator.def (UNOP_FORTRAN_RANK): New operator. gdb/testsuite/ChangeLog: * gdb.fortran/rank.exp: New file. * gdb.fortran/rank.f90: New file.
