All these built-in functions should be documented with @deftypefn, as is 
already done with many non-target-dependent built-in functions:

@deftypefn {Built-in Function} {v8qi} __builtin_ia32_paddb (v8qi @var{arg1}, v8qi @var{arg2})
...
@end deftypefn

(You might have more descriptive argument names; and perhaps "MMX Built-in
Function" would be better than plain "Built-in Function".)

Likewise.
