byte-swapping unnecessary. Add -sparclite-board option for
emulating RAM found on typical SPARClite boards. Print
error message for unrecognized option.

mememory_read and memory_write.

byte order instead of storing words in host byte order; this
greatly simplifies support of little-endian programs.

byte order instead of host byte order.
(byte_swap_words): Remove, no longer needed.

* sis.c (run_sim): Use revamped memory_read, which makes
byte-swapping unnecessary.
* exec.c (dispatch_instruction): Use revamped memory_read, which
makes byte-swapping and double-word fetching unnecessary.
* func.c (sparclite_board): Declare new variable.
(get_regi): Handle little-endian data.
(bfd_load): Recognize little-endian SPARClite as having
little-endian data.
* armos.c (ARMul_OSHandleSWI::SWI_Open): Handle special case
of ":tt" to catch stdin in addition to stdout.
(ARMul_OSHandleSWI::SWI_Seek): Return 0 or 1 to indicate failure
or success of lseek().
From PR 15839, modified a bit by me to appease my sense of style--but
not too much because I am lazy.
