* regcache.c (struct regcache_descr): Add field register_type.
(init_legacy_regcache_descr): Pass a pre-allocated regcache_descr
in as a parameter
(init_regcache_descr): Initialize register_type. Pass the descr
to init_legacy_regcache_descr. Use register_type instead of
REGISTER_VIRTUAL_TYPE.
(register_type): New function.
(regcache_dump): Replace REGISTER_VIRTUAL_TYPE with register_type.
* regcache.h (register_type): Declare.
