* config/v850/v850-opts.h: New.
* config/v850/v850.c (small_memory): Replace with
small_memory_physical_max array. Make that array static const.
(v850_handle_memory_option): Take integer value of argument. Take
gcc_options pointer, option text and location. Return void.
Update for changes to small memory structures.
(v850_handle_option): Access target_flags via opts pointer. Don't
assert that global structures are in use. Update calls to
v850_handle_memory_option.
(v850_encode_data_area): Update references to small memory
settings.
* config/v850/v850.h (struct small_memory_info, small_memory):
Remove.
(enum small_memory_type): Move to v850-opts.h.
* config/v850/v850.opt (config/v850/v850-opts.h): New
HeaderInclude entry.
(small_memory_max): New Variable entry.
(msda): Replace by pair of options msda= and msda-. Use UInteger.
(mtda, mzda): Likewise.
