Log Message:
lint: do not allow type attributes after label
After a label, the type attributes _Alignas, __packed and _Noreturn do
not make sense, so don't allow them. The only kind of attributes that
makes sense there syntactically is GCC __attribute__. Allow multiple
such attributes, like everywhere in the GCC grammar.
