Introduce ada_wrapped_operation
This adds class ada_wrapped_operation, which is used to wrap some generic operations with a bit of Ada-specific handling. This corresponds to the old "default" case in ada_evaluate_subexp. gdb/ChangeLog 2021-03-08 Tom Tromey <tom@tromey.com> * ada-lang.c (ada_wrapped_operation::evaluate): New method. * ada-exp.h: New file.
