Prior to this commit, all qstrs were required to be allocated (by calling mp_emit_common_use_qstr) in the MP_PASS_SCOPE pass (the first one). But this is an unnecessary restriction, which is lifted by this commit. Lifting the restriction simplifies the compiler because it can allocate qstrs in later passes. This also generates better code, because in some cases (eg when a variable is closed over) the scope of an identifier is not known until a bit later and then the identifier no longer needs its qstr allocated in the global table. Code size is reduced for all ports with this commit. Signed-off-by: Damien George <damien@micropython.org>
