Introduce class operation
This patch introduces class operation, the new base class for all
expression operations.
In the new approach, an operation is simply a class that presents a
certain interface. Operations own their operands, and management is
done via unique_ptr.
The operation interface is largely ad hoc, based on the evolution of
expression handling in GDB. Parts (for example,
evaluate_with_coercion) are probably redundant; however I took this
approach to try to avoid mixing different kinds of refactorings.
In some specific situations, rather than add a generic method across
the entire operation class hierarchy, I chose instead to use
dynamic_cast and specialized methods on certain concrete subclasses.
This will appear in some subsequent patches.
One goal of this work is to avoid the kinds of easy-to-make errors
that affected the old implementation. To this end, some helper
subclasses are also added here. These helpers automate the
implementation of the 'dump', 'uses_objfile', and 'constant_p'
methods. Nearly every concrete operation that is subsequently added
will use these facilities. (Note that the 'dump' implementation is
only outlined here, the body appears in the next patch.)
