class_docstr: Like TestLowerCPUAccessibleScope, but with a DeclBuffer.
  
  When the Allocate is updated, the DeclBuffer should not contain a
  dangling reference.
code: def expected():
      ptr: T.handle(
          "float32", "global.test_with_head_address"
      ) = T.call_extern(  # noqa: F722
          "handle", "dummy_head_address"
      )
      buf = T.decl_buffer(
          16, "float32", scope="global.test_with_head_address", data=ptr
      )
      T.evaluate(ptr)
