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.)

Make valgrind tests more robust by adding --wait=1 to vgdb invocation
On my setup some valgrind tests failed somewhat reliably because
the target remote | vgdb command couldn't find the vgdb-pipe files
because valgrind startup hadn't finished yet.
I tried to fix this by replacing the "Memcheck, a memory error detector"
match to "TO DEBUG THIS PROCESS USING GDB: start GDB like this" which is
right before valgrind creates the vgdb-pipe files. But even that didn't
guarantee that the vgdb-pipe files were there (maybe valgrind should
print that text after it has created them?). But also not all tests
use --vgdb-error=0, so the text isn't always printed.
To make the tests reliable I added --wait=1 to the vgdb invocation.
That tells vgdb to try to find the vgdb-pipe files, and if they aren't
there yet, to wait 1 second and try again.

In more detail, this commit adds a NT_RISCV_CSR note type. The
