I think it only makes sense to mark it as not experimental when the sub extensions get marked as frozen in the main isa spec document.

As far as this change is concerned, it looks good to me, but I think this should only land when all parts are 0.93 compatible. Given we support this extension via clang and require 0.92 to be set, I'm reluctant to have the compiler in a half-0.92/half-0.93 state, especially so close to LLVM 12 branching.
