(hppa_fallback_frame_prev_register)
(hppa_stub_frame_prev_register): Change type of last argument to
`gdb_byte *'.
(hppa_fetch_pointer_argument): Tweak comment.  Use
get_frame_register_unsigned instead of get_frame_register.
(hppa32_return_value, hppa64_return_value): Change type of readbuf
and writebuf arguments to `gdb_byte *'.  Remove unecessary casts
and local variables.
(hppa_pseudo_register_read): Change type of last argument to
`gdb_byte *'.
