for the reserved data-pointer is returned. That identifer should
be saved in a local static variable.
The per-architecture data-pointer can be initialized in one of two
ways: The value can be set explicitly using a call to
set_gdbarch_data(); the value can be set implicitly using the value
returned by a non-NULL INIT() callback. INIT(), when non-NULL is
called after the basic architecture vector has been created.
The per-architecture data-pointer is either initialized explicitly
(set_gdbarch_data()) or implicitly (by INIT() via a call to
gdbarch_data()). FREE() is called to delete either an existing
data-poitner overridden by set_gdbarch_data() or when the
architecture object is being deleted.
When a previously created architecture is re-selected, the
per-architecture data-pointer for that previous architecture is
restored. INIT() is not called.
During initialization, multiple assignments of the data-pointer are
allowed, non-NULL values are deleted by calling FREE(). If the
architecture is deleted using gdbarch_free() all non-NULL data
pointers are also deleted using FREE().

Multiple registrarants for any architecture are allowed (and
strongly encouraged). */
