Not sure if there's enough support to update all of them but, but many of the following should be extended to cover the new types:

clang/test/CodeGenCXX/aarch64-sve-vector-init.cpp
clang/test/CodeGenCXX/aarch64-mangle-sve-fixed-vectors.cpp
clang/test/CodeGenCXX/aarch64-mangle-sve-vectors.cpp
clang/test/CodeGenCXX/aarch64-sve-fixedtypeinfo.cpp
clang/test/CodeGenCXX/aarch64-sve-typeinfo.cpp
clang/test/AST/ast-dump-aarch64-sve-types.c
clang/test/CodeGen/aarch64-sve.c
clang/test/CodeGenObjC/aarch64-sve-types.m
clang/test/Sema/aarch64-sve-types.c
clang/test/Sema/attr-arm-sve-vector-bits.c
clang/test/SemaObjC/aarch64-sve-types.m

Is it worth adding the tuple types as well? I'm happy for that to be a separate PR but I figure you'll be touching the same files so it might be easier done together.  Your choice.
