* target.h (struct target_ops): removed to_convert_to_virtual and 

to_convert_from_virtual elements.  Initializations removed from
all static initializations.
(target_convert_to_virtual, target_convert_from_virtual):
removed.
(host_convert_to_virtual, host_convert_from_virtual):  Removed
forward declarations.
* target.c (cleanup_target): removed default assignments for
to_convert_to_virtual and to_convert_from_virtual.
* inftarg.c (host_convert_to_virtual, host_convert_from_virtual):
removed.
* findvar.c (value_of_register, value_from_register):
target_convert_to_virtual inlined.
* infcmd.c (do_registers_info):  target_convert_to_virtual inlined.
* valops.c (value_assign):  target_convert_from_virtual inlined.
