7b4330191f py, compiler: Fix up creation of default positionals tuple. 
With new order of evaluation of defaults, creating the tuple was done in
the wrong spot.

69b89d21b2 py: Change compile order for default positional and keyword args. 
This simplifies the compiler a little, since now it can do 1 pass over
a function declaration, to determine default arguments.  I would have
done this originally, but CPython 3.3 somehow had the default keyword
args compiled before the default position args (even though they appear
in the other order in the text of the script), and I thought it was
important to have the same order of execution when evaluating default
arguments.  CPython 3.4 has changed the order to the more obvious one,
so we can also change.

57e99ebc86 py: Add simple way of looking up constants in compiler. 
Working towards trying to support compile-time constants (see discussion
in issue #227), this patch allows the compiler to look inside arbitrary
uPy objects at compile time.  The objects to search are given by the
macro MICROPY_EXTRA_CONSTANTS (so they must be constant/ROM objects),
and the constant folding occures on forms base.attr (both base and attr
must be id's).

It works, but it breaks strict CPython compatibility, since the lookup
will succeed even without importing the namespace.

069a35e3a5 py, compiler: Improve stack depth counting. 
Much less of a hack now.  Hopefully it's correct!

6f355fd3b9 py: Make labels unsigned ints (converted from int). 
Labels should never be negative, and this modified type signature

882b363564 py: Move to Python 3.4.0 compatibility. 
Very little has changed.  In Python 3.4 they removed the opcode
STORE_LOCALS, but in Micro Python we only ever used this for CPython
compatibility, so it was a trivial thing to remove.  It also allowed to
clean up some dead code (eg the 0xdeadbeef in class construction), and
now class builders use 1 less stack word.

Python 3.4.0 introduced the LOAD_CLASSDEREF opcode, which I have not
yet understood.  Still, all tests (apart from bytecode test) still pass.
Bytecode tests needs some more attention, but they are not that
important anymore.

3ff2d03891 py: Fix bug in optimised for .. range. 
Don't store final, failing value to the loop variable.  This fix also
makes for .. range a bit more efficient, as it uses less store/load
pairs for the loop variable.

96eec4f8a6 compile: Don't try to constant-fold division by zero. 
The way it is, just crashes app. And optimizing to
"raise ZeroDivisionError" is probably too much.

d17926db71 Rename rt_* to mp_*. 
Mostly just a global search and replace.  Except rt_is_true which
becomes mp_obj_is_true.

Still would like to tidy up some of the names, but this will do for now.

d1e443d0bc py: Free unique_code slot for outer module. 
Partly (very partly!) addresses issue #386.  Most importantly, at the
REPL command line, each invocation does not now lead to increased memory
usage (unless you define a function/lambda).

bbf0e2fe12 parse: Note that fact that parser's small ints are different than VM small int. 
Specifically, VM's small ints are 31 bit, while parser's only 28. There's already
MP_OBJ_FITS_SMALL_INT(), so, for clarity, rename MP_FIT_SMALL_INT() to
MP_PARSE_FITS_SMALL_INT().
