We have bring up it to llvm-dev.
BTW,** All the Type should see as target independent.** (Even it support by less targets or 1 target)

Current we see  “ if (Ty.isVectorTy()) {…}” is make sense in Mid-End. 
Why we can’t see “if (Ty.isX86_AMXTy()){…}” is make sense ?

**Just because more targets support the VectorTy, less target (only x86) support the AMXTy ?
The logic is not make sense.**
