Implement several Fortran operations

Browse source 
This implements several straightforward Fortran operations, primarily
by reusing existing template classes.

gdb/ChangeLog
2021-03-08  Tom Tromey  <tom@tromey.com>

	* f-lang.c (eval_op_f_abs, eval_op_f_mod, eval_op_f_ceil)
	(eval_op_f_floor, eval_op_f_modulo, eval_op_f_cmplx)
	(eval_op_f_kind): No longer static.  Add "opcode" parameter.
	(evaluate_subexp_f): Update.
	* f-exp.h: New file.
