gdb/python: Add gdb.Architecture.registers method
This commit adds a new method gdb.Architecture.registers that returns
an object of the new type gdb.RegisterDescriptorIterator. This
iterator returns objects of the new type gdb.RegisterDescriptor.
A RegisterDescriptor is not a way to read the value of a register,
this is already covered by Frame.read_register, a RegisterDescriptor
is simply a way to discover from Python, which registers are
available for a given architecture.
I did consider just returning a string, the name of each register,
instead of a RegisterDescriptor, however, I'm aware that it we don't
want to break the existing Python API in any way, so if I return just
a string now, but in the future we want more information about a
register then we would have to add a second API to get that
information. By going straight to a descriptor object now, it is easy
to add additional properties in the future should we wish to.
Right now the only property of a register that a user can access is
the name of the register.
In future we might want to be able to ask the register about is
register groups, or its type.
