Introduce structop_operation
This adds class structop_base_operation and structop_operation, which
implement STRUCTOP_STRUCT. The base class exists to unify the
completion code between STRUCTOP_STRUCT and STRUCTOP_PTR.
gdb/ChangeLog
2021-03-08 Tom Tromey <tom@tromey.com>
* expop.h (class structop_base_operation)
(class structop_operation): New.
* eval.c (eval_op_structop_struct): No longer static.
