Clean up the D10V port so that GDB and the target program no

longer disagree on how big pointers are.
* findvar.c (value_from_register): Remove special case code for D10V.
* printcmd.c (print_frame_args): Same.
* valops.c (value_at, value_fetch_lazy): Same.
* values.c (unpack_long): Same.
* gdbarch.sh: Changes to effect the following:
* gdbarch.h (GDB_TARGET_IS_D10V, D10V_MAKE_DADDR,
gdbarch_d10v_make_daddr_ftype, gdbarch_d10v_make_daddr,
set_gdbarch_d10v_make_daddr, D10V_MAKE_IADDR,
gdbarch_d10v_make_iaddr_ftype, gdbarch_d10v_make_iaddr,
set_gdbarch_d10v_make_iaddr, D10V_DADDR_P,
gdbarch_d10v_daddr_p_ftype, gdbarch_d10v_daddr_p,
set_gdbarch_d10v_daddr_p, D10V_IADDR_P,
gdbarch_d10v_iaddr_p_ftype, gdbarch_d10v_iaddr_p,
set_gdbarch_d10v_iaddr_p, D10V_CONVERT_DADDR_TO_RAW,
gdbarch_d10v_convert_daddr_to_raw_ftype,
gdbarch_d10v_convert_daddr_to_raw,
set_gdbarch_d10v_convert_daddr_to_raw, D10V_CONVERT_IADDR_TO_RAW,
gdbarch_d10v_convert_iaddr_to_raw_ftype,
gdbarch_d10v_convert_iaddr_to_raw,
set_gdbarch_d10v_convert_iaddr_to_raw): Delete declarations.
* gdbarch.c: Delete the corresponding definitions.
(struct gdbarch): Delete members d10v_make_daddr,
d10v_make_iaddr, d10v_daddr_p, d10v_iaddr_p,
d10v_convert_daddr_to_raw, and d10v_convert_iaddr_to_raw.
(startup_gdbarch): Remove initializers for the above.
(verify_gdbarch, gdbarch_dump): Don't verify or dump them any
more.
* d10v-tdep.c (d10v_register_virtual_type): Rather that
claiming the stack pointer and PC are 32 bits long (which they
aren't), say that the stack pointer is an int16_t, and the
program counter is a function pointer.  This allows the rest
of GDB to make the appropriate conversions between the code
pointer format and real addresses.
(d10v_register_convertible, d10v_register_convert_to_virtual,
d10v_register_convert_to_raw): Delete function; no registers
are convertible now, so we use
generic_register_convertible_not instead.
(d10v_address_to_pointer, d10v_pointer_to_address): New gdbarch
methods.
(d10v_push_arguments, d10v_extract_return_value): Remove special
cases for code and data pointers.
(d10v_gdbarch_init): Set gdbarch_ptr_bit to 16, so that GDB and
the target agree on how large pointers are.  Say that addresses
are 32 bits long.  Register the address_to_pointer and
pointer_to_address conversion functions.  Since no registers are
convertible now, register generic_register_convertible_not as the
gdbarch_register_convertible method instead of
d10v_register_convertible.  Remove registrations for
d10v_register_convert_to_virtual,
d10v_register_convert_to_raw, gdbarch_d10v_make_daddr,
gdbarch_d10v_make_iaddr, gdbarch_d10v_daddr_p,
gdbarch_d10v_iaddr_p, gdbarch_d10v_convert_daddr_to_raw, and
gdbarch_d10v_convert_iaddr_to_raw.
