unsigned types.
Specify size of r5900 FSR using 32 bit unsigned type.
Correctly format mips registers when some are not 64 bits in size
Check that REGISTER_{RAW,VIRTUAL}_SIZE are consistent when the target
specifies that no conversion is needed when moving from one to the
other.

start-sanitize-r5900
* config/mips/tm-r5900.h (REGISTER_VIRTUAL_SIZE): Redefine as
expression from REGISTER_VIRTUAL_TYPE.
(REGISTER_RAW_SIZE): Ditto.
(REGISTER_VIRTUAL_TYPE): Redefine, use explicit size for 32 bit
registers.
end-sanitize-r5900
* gdbtypes.h (builtin_type_{,u}int{8,16,32,64}): New gdb builtin
types.
start-sanitize-r5900
(builtin_type_{,u}int128): Ditto.
end-sanitize-r5900
* gdbtypes.c (_initialize_gdbtypes): Initialize new types.
* mips-tdep.c (do_gp_register_row): Pad register value when GP
register is smaller than MIPS_REGSIZE.
* findvar.c (value_of_register): When raw and virtual register
values identical, check that sizes are consistent.
