Another followup to D136939, adding default attributes to the remaining readnone intrinsics.
This also covers some non-readnone pmovqw*mem_mask style intrinsics, because those were interleaved, and it seemed to make more sense to update them at the same time.
Actually, only this single one is AMX intrinsic. We do need a comment for the following ones. I'll do it later.
It is reasonable to take care of AMX intrinsic, so I have excluded this one in the comments :)
I think it's OK to leave it the same as other AMX intrinsics. @yubing any suggestions for these AMX intrinsics?
