... instead we start to use regcache methods save and restore.  It is
quite straightforward to replace regcache_save with regcache->save.

regcache_cpy has some asserts, some of them not necessary, like

 gdb_assert (src != dst);

because we already assert !m_readonly_p and src->m_readonly_p, so
src isn't dst.  Some of the asserts are moved to ::restore.
