Thanks for your advice, I have misunderstood what you meant.
I have sent a second version patch, please review whether it is OK.

This patch adds type checking for static local vector variable in
C++ template, both AArch64 SVE and RISCV RVV are of sizeless type

I was thinking to move the verify_type_context code from start_decl,
which handles more cases:
if (is_global_var (decl))
{
type_context_kind context = (DECL_THREAD_LOCAL_P (decl)
? TCTX_THREAD_STORAGE
: TCTX_STATIC_STORAGE);
verify_type_context (input_location, context, TREE_TYPE (decl));
}
