d8675541a9 py, vm: Where possible, make variables local to each opcode. 
This helps the compiler do its optimisation, makes it clear which
variables are local per opcode and which global, and makes it consistent
when extra variables are needed in an opcode (in addition to old obj1,
obj2 pair, for example).

Could also make unum local, but that's for another time.

f600a6a085 py: Slightly improve efficiency of mp_obj_new_str; rename str_new. 
Reorder interning logic in mp_obj_new_str, to be more efficient.

str_new is globally accessible, so should be prefixed with mp_obj_.

2617eebf2f Change const byte* to const char* where sensible. 
This removes need for some casts (at least, more than it adds need
for new casts!).

5042bce8fb py: Don't automatically intern strings in parser. 
This completes non-automatic interning of strings in the parser, so that
doc strings don't take up RAM.  It complicates the parser and compiler,
and bloats stmhal by about 300 bytes.  It's complicated because now
there are 2 kinds of parse-nodes that can be strings: interned leaves
and non-interned structs.

806ea1f6ca py: Initial attempts to actually allow implementing __new__ in Python. 
Caveat is that __new__ should recurse to base class __new__, and ultimately,
object.__new__ is what handles instance allocation.

9e29666bf9 py: Implement proper separation between io.FileIO and io.TextIOWrapper. 
io.FileIO is binary I/O, ans actually optional. Default file type is
io.TextIOWrapper, which provides str results. CPython3 explicitly describes
io.TextIOWrapper as buffered I/O, but we don't have buffering support yet
anyway.

13684fd60b objtype: Separate __new__ and __init__ methods. 
Now schedule is: for native types, we call ->make_new() C-level method, which
should perform actions of __new__ and __init__ (note that this is not
compliant, but is efficient), but for user types, __new__ and __init__ are
called as expected.

Also, make sure we convert scalar attribute value to a bound-pair tight in
mp_obj_class_lookup() method, which avoids converting it again and again in
its callers.
